Jose Olarte III 84983ee10b refactor(shared-image): replace temp file approach with native Capacitor plugins ...

Replace the buggy temp file polling mechanism with direct native-to-JS
communication via custom Capacitor plugins for iOS and Android. This
eliminates race conditions, file management complexity, and polling overhead.

BREAKING CHANGE: Removes backward compatibility with temp file approach.
Android minSdkVersion upgraded from 22 to 23.

Changes:
- iOS: Created SharedImagePlugin (CAPBridgedPlugin) and SharedImageUtility
  - Uses App Group UserDefaults for data sharing between extension and app
  - Implements getSharedImage() and hasSharedImage() methods
  - Removes temp file writing/reading logic from AppDelegate
- Android: Created SharedImagePlugin with @CapacitorPlugin annotation
  - Uses SharedPreferences for data storage instead of temp files
  - Implements same interface as iOS plugin
  - Removes temp file handling from MainActivity
- TypeScript: Added plugin definitions and registration
  - Created SharedImagePlugin interface and web fallback
  - Updated main.capacitor.ts to use plugin instead of Filesystem API
  - Removed pollForFileExistence() and related file I/O code
- Android: Upgraded minSdkVersion from 22 to 23
  - Required for SharedPreferences improvements and better API support

Benefits:
- Eliminates race conditions from file polling
- Removes file cleanup complexity
- Direct native-to-JS communication (no file I/O)
- Better performance (no polling overhead)
- More reliable data transfer between share extension and app
- Cleaner architecture with proper plugin abstraction
