Adds an optional MCP server (proprietary module) that exposes Stirling's
PDF operations and AI capabilities to MCP clients. Off by default, zero
footprint when disabled.
### What
- New `/mcp` endpoint: streamable-HTTP + JSON-RPC 2.0; 8 tools
(describe_operation, pages/convert/misc/security category tools, AI,
upload, download).
- Runs real operations over an internal loopback; results returned
inline as base64 (small) or by fileId (large).
### Auth (two modes)
- OAuth2 resource server: RFC 9728 protected-resource metadata, RFC 8707
audience binding, JWKS, `mcp.tools.read/write` scopes; binds each token
to a provisioned Stirling account.
- API-key mode: reuses Stirling per-user `X-API-KEY` (no IdP needed).
### Security
- Per-user file ownership in FileStorage: async/queued writes scoped to
the submitting user; legacy/owner-less files stay readable.
- Admin allow/block list controls which operations are exposed.
- Python engine gated behind a shared secret (`X-Engine-Auth`).
- MCP filter chain is isolated and cannot weaken the main app's
security.
- Hardened: no upstream error-body leakage, log injection sanitized,
fileId path/sidecar enumeration blocked.
### Config / footprint
- Disabled by default (`mcp.enabled=false`); all beans
`@ConditionalOnProperty`.

# Description of Changes
- Tool action button truncation - fixed by allowing Mantine <Button>
label to wrap (whiteSpace: normal, height: auto) instead of clipping
- Role badge truncation on People page - fixed by dropping the column's
fixed w={100} and letting the badge size to its content
- Settings nav item wraps to 3 lines - fixed by hiding the inline ALPHA
badge by default and revealing it on :hover/:focus-within/.active
- Zoom slider cramped on narrow desktop - fixed by removing the
toolbar's hardcoded minWidth: 30rem and giving the slider flexShrink: 0
+ minWidth: 6rem
- "Swipe left or right" hint on desktop - fixed by adding a useIsTouch()
hook (pointer: coarse) and gating the hint on isMobile && isTouch
- Logout doesn't redirect - fixed by replacing navigate('/login') with
window.location.assign('/login') in a finally block so auth context
fully re-bootstraps
- Viewer top toolbar clips icons on mobile - fixed by switching the
wrapped state to justify-content: flex-start + overflow-x: auto so the
icon strip is momentum-scrollable
- Mobile bottom toolbar overflows - fixed by gating layout on
useIsPhone() and reducing the inline bar to prev / page / next / ⋮ only
- Lost controls when shrinking mobile toolbar - fixed by adding a
Mantine <Menu> behind ⋮ that groups First/Last page, Zoom in/out (with
%), Dual-page, Dark/Sepia filter under Page navigation / Zoom / View
labels
- "Upload from computer" label clipped on hover - fixed by unmounting
the Add Files button entirely while Upload is hovered, so Upload claims
width: 100%
- Settings rows clip controls off-screen - fixed by adding flex: 1,
minWidth: 0 to the inner text-block <div> on 44 rows across 10 -files,
so labels shrink and wrap while controls stay anchored to the right

# Description of Changes
Disallow warnings and errors from being thrown in the browser console
during tests unless explicitly expected in the test. Also adds a
Playwright test to prod around some main UI areas and checks that no
warnings/errors have been thrown.
## Summary
Make the remaining static ENTERPRISE badges in the admin settings
clickable so they navigate the user to `/settings/adminPlan`, matching
the pattern already used by the PRO badges in Connections / Features /
General sections.
### Before
Two ENTERPRISE badges were inert text chips with no affordance:
- `AdminSecuritySection.tsx` - Audit Logging
- `AdminDatabaseSection.tsx` - Database section header
### After
Both now use the same pattern as the existing clickable PRO badges:
- `cursor: pointer`
- `onClick={() => navigate("/settings/adminPlan")}`
- `title` tooltip with the existing
`admin.settings.badge.clickToUpgrade` i18n key ("Click to view plan
details")
No new strings, no new components - just wiring up existing behavior to
the two badges that were missing it.
### Existing already-clickable badges (kept identical for reference)
- `AdminConnectionsSection.tsx:585-596` - SSO Auto Login PRO
- `AdminFeaturesSection.tsx:175-186` - Server Certificate PRO
- `AdminGeneralSection.tsx:920-931` - Custom Metadata PRO
## Summary
Audit + bulk fix of hard-coded English UI strings - `aria-label`,
`title`, `placeholder`, `label`, and raw JSX literals that bypassed i18n
entirely. Each literal now goes through `t("key", "English Default")`
from `react-i18next`, and every new key has a corresponding entry in
`en-GB/translation.toml` so translators can pick it up.
## What this fixes
Strings were rendered untranslated in every non-EN locale because they
never went through `t()` at all (not just "value not translated yet").
Affects screen-reader labels, tooltips, form placeholders, empty/loading
states, plan card content, and the entire workflow ParticipantView.
## Coverage (~143 keys / 50 files)
- **Viewer chrome** - search bar (close, clear, prev/next, "of N"
results), link/signature/redaction actions, viewer error state, zoom
labels
- **Page editor** - undo/redo/rotate/delete toolbar tooltips, empty
state, bulk selection operator chip tooltips
- **Shared primitives** - Tooltip close, InfoBanner dismiss, TextInput
clear, Toast dismiss/toggle, UpdateModal close, EditableSecretField
edit, DropdownListWithFooter search, FileCard/FileDropdownMenu actions,
EmptyFilesState + AddFileCard upload
- **Tools** - Image upload + hint, ColorControl eyedropper, sign Use
Signature, CompressSettings, OCR loading, PageLayout
margin/border/row/col placeholders, FormFill switch + save + re-scan
- **Proprietary admin** - OverviewHeader signed-in line + logout,
AdminPremiumSection moved-features list (via `<Trans>`),
AdminPlanSection no-data alert, AdminAdvancedSection temp-dir
placeholders, AdminEndpointsSection multiselect placeholders,
AdminMailSection + AdminDatabaseSection password placeholders
- **Onboarding** - MFASetupSlide QR loading + auth code label,
SecurityCheckSlide role select + options
- **ParticipantView** - entire sign-document UI (~30 strings: loading,
error, badges, headings, cert-type Select, all input labels and
placeholders, action buttons, completion + expired alerts) - file
previously imported `useTranslation` but only used `t()` for cert
validation
- **planConstants.ts refactor** - replaced `PLAN_FEATURES` /
`PLAN_HIGHLIGHTS` const exports with `usePlanFeatures()` /
`usePlanHighlights()` hooks. Service layer (`licenseService.getPlans`)
updated to accept feature/highlight maps so it stays hook-free. Callers
(`usePlans`, `CheckoutContext`) resolve the hooks at the React boundary
- **Previously catalogued offenders** - `FileSidebarFileItem`
open/close-viewer aria-labels, `quickAccessBar/ActiveToolButton` "Back
to all tools" tooltip + aria, `AppConfigModal` close button
## Notes
- One small refactor in `usePageSelectionTips.ts` was needed to resolve
a TOML key-shape conflict: the existing scalar keys
`bulkSelection.operators.{and,not,comma}` needed to become tables to
hold the new `.title` subkeys for OperatorsSection's chip tooltips. The
existing descriptions moved to `[bulkSelection.operators.descriptions]`
and the three i18n key paths in usePageSelectionTips were updated to
match.
- Viewer sidebar close buttons
(Bookmark/Layer/Thumbnail/Attachment/Comments) were on the audit list
but are NOT on main - they're added by the unmerged PR #6552
(feat/viewer-sidebar-ux). Those particular strings will need wrapping
when that PR lands.
- TOML hook (`toml-sort-fix`) ran and re-sorted the translation file.
## Test plan
- [ ] `task frontend:typecheck` passes (core + proprietary + desktop
variants)
- [ ] `task frontend:lint` passes
- [ ] Switching language to Deutsch / Русский: previously-English
`aria-label`s + tooltips + placeholders + plan card bullets now render
translated (when the locale has values) or fall back to the English
default (when it doesn't)
- [ ] Plan page bullet points in EN render unchanged
- [ ] Sign-document flow (ParticipantView) renders unchanged in EN
