fix(verify-pdf): verification to properly detect non-PDF/A documents with XMP metadata (#5397)

# Description of Changes

Fixed an issue where PDFs containing XMP metadata but lacking PDF/A
identification schema were incorrectly being validated as PDF/A
documents and reporting "PDF/A-1b with errors" instead of "NOT PDF/A".

### Changes Made
- Improved the PDF/A detection logic in `VeraPDFService.java` to check
for both missing XMP metadata and missing PDF/A identification schema
- Added validation for clause 6.7.11 (PDF/A Identification extension
schema requirement) in addition to clause 6.7.2 (XMP metadata presence)
- Documents with XMP metadata but without proper PDF/A identification
now correctly return "NOT PDF/A"

### Root Cause
The previous implementation only checked for missing XMP metadata
(clause 6.7.2) but didn't verify that the XMP contained the required
PDF/A identification schema (clause 6.7.11). This caused documents with
generic XMP metadata to be incorrectly treated as declared PDF/A files.

Fixes issue where non-PDF/A documents with XMP metadata were incorrectly
showing PDF/A validation errors.
