### Motivation
- Allow operators to configure a pipeline base directory and multiple
watched folders so the pipeline can monitor several directories and
subdirectories concurrently.
- Ensure scanning traverses subdirectories while skipping internal
processing folders (e.g. `processing`) and preserve existing behavior
for finished/output paths.
- Expose the new options in the server `settings.yml.template` and the
admin UI so paths can be edited from the web console.
### Description
- Added new `pipelineDir` and `watchedFoldersDirs` fields to
`ApplicationProperties.CustomPaths.Pipeline` and kept backward
compatibility with `watchedFoldersDir`
(app/common/src/main/java/stirling/software/common/model/ApplicationProperties.java).
- Resolved pipeline base and multiple watched folder paths in
`RuntimePathConfig` and exposed `getPipelineWatchedFoldersPaths()`
(app/common/src/main/java/stirling/software/common/configuration/RuntimePathConfig.java).
- Updated `FileMonitor` to accept and register multiple root paths
instead of a single root
(app/common/src/main/java/stirling/software/common/util/FileMonitor.java).
- Updated `PipelineDirectoryProcessor` to iterate all configured watched
roots and to walk subdirectories while ignoring `processing` dirs
(app/core/src/main/java/stirling/software/SPDF/controller/api/pipeline/PipelineDirectoryProcessor.java).
- Exposed the new settings in `settings.yml.template` and the admin UI,
including a multi-line `Textarea` to edit `watchedFoldersDirs`
(app/core/src/main/resources/settings.yml.template,
frontend/src/proprietary/components/shared/config/configSections/AdminGeneralSection.tsx).
- Adjusted unit test setup to account for list-based watched folders
(app/common/src/test/java/stirling/software/common/util/FileMonitorTest.java).
### Testing
- Ran formatting and build checks with `./gradlew spotlessApply` and
`./gradlew build` using Java 21 via
`JAVA_HOME=/root/.local/share/mise/installs/java/21.0.2
PATH=/root/.local/share/mise/installs/java/21.0.2/bin:$PATH ./gradlew
...`, but both runs failed due to Gradle plugin resolution being blocked
in this environment (plugin portal/network 403), so full
compilation/formatting could not complete.
- Confirmed the code compiles locally was not possible here; unit test
`FileMonitorTest` was updated to use the new API but was not executed
due to the blocked build.
- Changes were committed (`Support multiple pipeline watch directories`)
and the repository diff contains the listed file modifications.

# Description of Changes
This pull request updates the authentication token refresh response
structure to include both user and session information, and makes
corresponding adjustments in the backend, frontend, and tests to support
this change. Additionally, it adds improved logging to the frontend for
better debugging.
**Backend API response changes:**
* The `/api/v1/auth/refresh` endpoint now returns a response containing
both a `user` object and a nested `session` object with the new access
token and expiry, instead of returning the token fields at the top
level.
**Test updates:**
* The `refreshReturnsNewTokenWhenValid` test has been updated to expect
the new response structure, checking for `session.access_token` and
`session.expires_in` instead of the previous top-level fields.
**Frontend improvements:**
* Added a debug log message in `springAuthClient.ts` to indicate when
the token has been refreshed successfully, aiding in debugging and
monitoring.

# Description of Changes
## What was changed
- Updated several Mantine `label` compositions in
`AdminSecuritySection.tsx` to avoid invalid HTML nesting that can
trigger React hydration errors (e.g., a `<div>` rendered inside a
`<p>`).
- Changed `Group` used inside `NumberInput` / `Select` labels to render
as an inline element via `component="span"`.
- Added `name` attributes to multiple form controls (`Switch`, `Select`,
`NumberInput`, `Textarea`) to satisfy browser/autofill recommendations
and improve form field identification.
## Why the change was made
- Fixes the runtime warning/error:
- `In HTML, <div> cannot be a descendant of <p>. This will cause a
hydration error.`
- Caused by block-level wrappers inside Mantine `Text`/`p` label
rendering.
- Addresses the browser audit warning:
- `A form field element should have an id or name attribute`
- Adding stable `name` attributes improves autofill behavior and form
accessibility tooling.

# Description of Changes
This pull request introduces several improvements and new features
across the authentication and admin data APIs, with a particular focus
on multi-factor authentication (MFA) support and better handling of user
settings. The changes include integrating MFA status into account data
responses, masking sensitive user settings in admin views, and
refactoring code to use more robust user creation methods. Additionally,
there are minor code cleanups and consistency improvements.
### Multi-factor Authentication (MFA) Integration
* Added `mfaEnabled` and `mfaRequired` fields to the `AccountData`
response, populated using the new `MfaService`, to provide clients with
MFA status information for users.

### User Settings Handling and Security
* Admin settings API now returns user settings for each user, with the
`mfaSecret` field masked to protect sensitive information. This is
achieved by fetching settings via `findByIdWithSettings` and
copying/masking the relevant field before returning.

### Refactoring and Code Consistency
* Refactored user creation in `InitialSecuritySetup` to use the
`SaveUserRequest` builder and `saveUserCore` for better maintainability
and clarity, replacing direct calls to `saveUser`.

### API and DTO Changes
* Changed the login API to accept `UsernameAndPassMfa` instead of
`UsernameAndPass`, paving the way for MFA code support in authentication
requests.

* Updated import statements and controller dependencies to include new
DTOs and services related to MFA.

# Description of Changes
This PR introduces comprehensive database backup and restore management
for embedded H2 databases directly within the admin UI, along with a
corrected backend condition for H2 detection.
### What was changed
- Fixed `H2SQLCondition` logic so embedded H2 is correctly detected when
custom databases are disabled.
- Updated and expanded unit tests to reflect the corrected H2 enablement
behavior.
- Added a new **Backups & Restore** section to the Admin Database
settings UI.
- Implemented UI features to:
- Create H2 database backups
- List available backup files with metadata
- Download, import, and delete existing backups
- Upload and import `.sql` backup files with a confirmation code safety
step
- Added a new frontend service (`databaseManagementService`) to
encapsulate database management API calls.
- Extended English (en-GB) translations for all new database backup and
restore UI elements.
### Why the change was made
- Embedded H2 is the default database when no custom database is
configured, but this was not consistently reflected in backend
conditions.
- Administrators need a safe, UI-driven way to manage H2 backups without
manual filesystem access.
- The new UI improves operability, safety (confirmation code on import),
and transparency (version and status badges).

# Description of Changes
### What was changed
- Added new admin-only API endpoints to:
- List installed tessdata OCR languages
- Fetch available tessdata languages from the official Tesseract
repository
- Download selected tessdata language files directly into the configured
tessdata directory
- Implemented server-side validation, safe language name handling, and
directory writability checks.
- Extended the Admin Advanced Settings UI to:
- Display installed tessdata languages
- Show available remote languages not yet installed
- Allow selecting and downloading additional languages via a
multi-select UI
- Gracefully fall back to manual download links when the tessdata
directory is not writable
- Added new i18n strings for all related UI states (loading, success,
error, permission warnings).
### Why the change was made
- Managing OCR languages previously required manual filesystem
interaction.
- This change improves usability for administrators by enabling in-app
management of tessdata languages while maintaining security constraints.
- The writable directory check and manual fallback ensure compatibility
with restricted or containerized environments.

# Description of Changes
This pull request introduces Telegram bot integration to the
application, enabling users to send files via Telegram for processing
through the pipeline. The main changes add configuration options,
dependency management, and a new service for handling Telegram
interactions.
**Telegram bot integration:**
* Added a new `TelegramPipelineBot` service (`TelegramPipelineBot.java`)
that listens for incoming Telegram messages, downloads attached files or
photos, places them in a pipeline inbox folder, waits for processing
results, and sends the output files back to the user. The service
includes error handling and status messaging.
* Introduced a `TelegramBotConfig` configuration class to initialize and
register the Telegram bot only when enabled via application properties.
* Added a new `Telegram` configuration section to
`ApplicationProperties` and the `settings.yml.template`, supporting
options like enabling/disabling the bot, bot token/username, pipeline
folder, processing timeout, and polling interval.

```
This pull request fixes a self-hosting issue where the Tauri HTTP client
fails with `Unexpected token ... is not valid JSON` because certain API
endpoints returned plain text responses.
## What was changed
- Updated `AdminSettingsController`:
- Changed `updateSettings` and `updateSettingsSection` to return
structured JSON objects instead of raw strings.
- Standardized success and error payloads using a `Map<String, Object>`
with keys like `message` and `error`.
- Updated `UserController`:
- Changed `/api/v1/user/get-api-key` and `/api/v1/user/update-api-key`
to return JSON objects (`{ "apiKey": "..." }`) and JSON error objects
instead of plain text.
## Why the change was made
- The Tauri client expects JSON responses and attempts to parse them.
Returning plain strings like `"Successful..."` or an API key string
causes JSON parsing to fail, resulting in network errors on self-hosted
setups.
