fix(gui): UI appearance polish — Wayland scaling, menu icon size pref, dialog cleanup

- Fix hazy text on Wayland by setting QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor
  and QT_ENABLE_HIGHDPI_SCALING=1 in deb and AppImage launchers; remove forced
  QT_QPA_PLATFORM=xcb from AppImage to allow native Wayland (fixes #33)

- Add menu icon size preference selector (Small/Medium/Large/Extra large) in
  General preferences, applied via QMenu stylesheet at startup and on save (fixes #46)

- Replace verbose theme customization banner with concise 'Kindred Create Theme'
  label in UI preferences; split Overlay group into 'Panel Visibility' and
  'Overlay Interaction' sections (fixes #35)

- Remove Addon Manager branding label from General preferences, change recent
  file list default from 4 to 10 (fixes #36)
