Release 1.7.0

- CHANGELOG: cut the 1.7.0 release (dated 2026-06-10); reset Unreleased.
- VERSION: 1.6.28 → 1.7.0.
- Manuals (DA + EN): bump version stamps; correct the redaction section
  (cards are now kept/greyed until the next scan, not removed) and add the
  same keep-until-next-scan note to the deletion section, including the
  partial-failure behaviour.

 ### Added
 
 - **PDF redaction for local files** — the ✂ redact button now works on local PDF files in addition to DOCX, XLSX, CSV, and TXT. Text-based PDFs are redacted using PyMuPDF's physical redaction (`page.apply_redactions()`), which removes the underlying text data from the PDF stream — not just paints over it. Scanned/image-based PDFs go through the OCR bbox path: CPR positions are found via Tesseract then physically painted and sanitised. Falls back to a reportlab overlay if PyMuPDF is not installed; raises a clear error if both libraries are absent.
