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

- 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.

+// The rule this file exists to enforce: OCR LANGUAGES TRACK INTERFACE LANGUAGES.
+// If MmdPdf's UI is offered in a language, OCR is offered in it too. There is no such thing as
+// an interface language whose text the app cannot read.
+//
+// Nothing enforced it before, so it drifted: the UI shipped hu-HU while the catalog stayed at
+// eleven entries, and baobab-ts.com went on telling people OCR covered ten languages and that
+// Polish and Hungarian "do not require OCR models".
+//
+// These read the real Strings folder instead of a second hardcoded list, so adding a locale fails
+// the build until its model is registered. release.ps1 runs the suite, so it cannot ship broken.
