0fd6a35562 fix(diff_report): _fmt_value labels italic flips correctly 
Previously every boolean attribute rendered as "Bold → Regular",
producing "Italic: Bold → Regular" for italic flips. Now the helper
takes the attribute name and emits "Italic → Regular" or
"Bold → Regular" depending on which boolean attribute is being shown.

7eaac85df3 feat(diff_report): render formatting_changes as a per-pair block 
Adds a "🎨 Formatting changes" block to the per-page diff report
when the deterministic formatting layer finds typographic flips.
Distinguishes page-wide style shifts from local span flips, lists up
to three example quotes per aggregated finding, and HTML-escapes all
user-controlled strings.

90563b8cf2 Add AXA document-mode QC pipeline (Phases 1, 3, 4, 5) 
Multi-page PDF QC for AXA Ireland policy documents. Runs as a third mode
alongside static + video, gated on profile.mode. New code isolated under
backend/document_mode/ with new endpoints under /api/document/*.

Phase 1 — Spine + 6 deterministic doc-scope checks ($0, runs in seconds):
- Scope-aware dispatcher (document/targeted/page_sample/page_pair/page_each)
- axa_font_inventory, axa_phone_inventory, axa_bold_words_definitions,
  axa_page_numbering, axa_print_code, axa_omg_versioning
- Bootstrap bold-words dictionary extracted from Example 1 General Definitions

Phase 3 — Old-vs-new diff (~$0.50/run, 3-5 min):
- Page alignment via difflib SequenceMatcher (windowed fuzzy match)
- Vision-LLM page-pair diff via Gemini 2.5 Pro (8 concurrent)
- Two-slot upload UX, axa_policy_document_diff profile, mode=document_diff

Phase 4 — PDF accessibility (PyMuPDF, $0):
- 9 PDF/UA-1 aligned criteria (tagged structure, /MarkInfo, title, /Lang,
  encryption, font embedding, PDF version, XMP UA-conformance, alt-text)
- _run_verapdf() stub for optional Java-based veraPDF integration later

Phase 5 — Print preflight (PyMuPDF, $0):
- 7 criteria (page geometry, bleed, image colour spaces, image DPI,
  transparency, PDF/X conformance, spot colours)

Profile additions:
- axa_policy_document — 8 deterministic checks, $0 cost
- axa_policy_document_diff — 1 page-pair LLM check, ~$0.50/run

API additions:
- POST /api/document/start_analysis (single PDF)
- POST /api/document/start_diff (old + new PDFs)

Frontend additions:
- Third profile.mode value (document_diff) in applyProfileMode()
- Two-slot upload UX with PDF-only file pickers
- checkFormValidity() branches by mode for the analyse-button gate

Smoke-tested locally against Example 1 (Home Insurance V8, 86pp) and
Example 2 (Landlord V1 vs V10, 68→74pp) with real findings caught
including bold-words gaps, missing PDF/UA flag, transparency on press,
V1→V10 bold-formatting fixes. Plan + integration map + gotchas in
backend/AXA_DOCUMENT_MODE_PLAN.md.
