feat(compliance): implement compliance verfication for get info on PDF (#5435)

# Description of Changes


This PR replaces the legacy, fragile PDF/A validation logic (which
relied on manual regex parsing and PDFBox Preflight) with the robust
**VeraPDF** integration. Additionally, it introduces a new check for
**SEC/EDGAR compliance** and refactors the frontend report view to
display detailed verification results.

### Key Changes

**Backend (`GetInfoOnPDF.java`):**

* **VeraPDF Integration:** Replaced the custom `checkForStandard` and
`validatePdfAWithPreflight` methods with `VeraPDFService.validatePDF()`.
This aligns validation with industry standards.
* **Code Cleanup:** Removed approximately ~200 lines of technical debt,
including raw XML regex parsing and file-locking prone `PreflightParser`
logic.
* **SEC Compliance:** Added `isSECCompliant()` logic to validate
documents against typical EDGAR requirements:
* No Encryption.
* No Active Content (JavaScript).
* No External Links.
* No Embedded Files.
* No AcroForms.



**Frontend (`GetPdfInfo`):**

* **New Component:** Created `ComplianceSection.tsx` to handle the
complexity of compliance reporting.
* **Enhanced UI:**
* Added visual badges (Passed/Failed/Not Detected) using
`CheckIcon`/`CloseIcon`.
* Added support for displaying the detailed VeraPDF summary alongside
legacy boolean flags.
* Improved handling of "Not PDF/A" states.


### Motivation

The previous validation logic was prone to false positives/negatives and
memory issues with large files (due to Preflight). Moving to VeraPDF
provides accurate, profile-based validation (e.g., PDF/A-1b, 2b, etc.).
The SEC check satisfies a growing need for users validating documents
for financial filings.
