perf(v1.8.0): optimize ProGuard/R8 rules for smaller APK size

Browse Source 
- Replace broad '-keep class dev.dettmer.simplenotes.** { *; }' with targeted rules
- Keep only Gson data models and enum values that require reflection
- Allow R8 to shrink/obfuscate remaining app code
- Update rules for: Note, ChecklistItem, DeletionTracker, BackupData models
- Keep enum values() and valueOf() for state serialization
- Remove unnecessary keep rules for non-reflection classes
- Add structured comments for maintainability

APK size reduced from 5.0 MB → 4.8 MB (200 KB saved).
R8 now has better optimization opportunities while maintaining functionality.
All unit tests pass, lint reports clean (0 errors, 0 warnings).

Build: BUILD SUCCESSFUL - 4.8M app-fdroid-release.apk
