feat: rebrand to MMD PDF, single corporate theme, and remove original text under an edit

Browse Source 
- Services/PdfRedactText.cs: strip text whose origin falls inside a CoverAnnotation
  from the page content stream at save time, hooked into PdfBurn.DrawAnnotationsIntoDoc.
  Fixes edited values staying recoverable by text extraction.
- Themes/MMD.xaml replaces all thirteen themes; picker and accent strip removed; no dark mode.
- Rename KillerPDF -> MMD PDF across code, resources, packaging and locale strings; new icon.
- Remove the upstream author credit and the in-app install button.

veraPDF run date: 2026-08-22, against the 1.7.5 release build. This small maintenance release

without changing the PDF serializer. The standard open/save pipeline was nevertheless run fresh

header case as the only flagged saved file. The qpdf sweep also reproduces its table exactly:

a GUI-subsystem binary, so a bare invocation returns immediately and the after-scan then
validates a half-written tree - every not-yet-written file shows up as MISSING_AFTER (this
burned the 1.7.0 run, twice).
The compare script counts every MISSING_AFTER as a regression by design, so a run with skips
exits 1 even when clean. The release bar is: every MISSING_AFTER row cross-checks against a
SKIP row in `resave.csv` (encrypted/unparseable files KillerPDF refuses to touch), and the
SKIP row in `resave.csv` (encrypted/unparseable files MmdPdf refuses to touch), and the
only rule-level change is the documented PDF/A-4 header case. Anything beyond that is a real
regression.
