fix(maui): scale and center Android adaptive app icon safe-zone, bump version to 1.3.2 (fixes #167)

[fboucher]

Summary of Changes

• Version Bump: Upgraded application version to v1.3.2 across Directory.Build.props and src/NoteBookmark.MauiApp/NoteBookmark.MauiApp.csproj (with ApplicationVersion incremented to 5).
• Android Adaptive App Icon Safe-Zone Fix: Adjusted scale factor in appiconfg.svg transform matrix from 0.853816 to 0.65 (tx = 280, ty = 253.325).
  • The previous scale factor (0.853816) caused artwork pixels to extend up to 371.9px from center, exceeding the Android adaptive icon safe-zone radius of 305.5px (cutting off top, bottom, and corners on Android home screens / app launcher).
  • The new scale factor (0.65) brings maximum artwork pixel distance from center to 283.09px, ensuring 100% of the icon artwork sits comfortably inside Android's adaptive icon mask (circular/squircle) with ~7% padding.

Fixes #167
