Subject: [PATCH] fix: Add comprehensive SQL parameter type conversion at
 platform service level

- Add parameter conversion in CapacitorPlatformService.queueOperation()
- Convert booleans to integers (0/1) for SQLite compatibility
- Convert objects/arrays to JSON strings for database storage
- Handle null/undefined values properly
- Ensure all SQL parameters are SQLite-compatible before queuing

This should resolve the 'SQLite3 can only bind numbers, strings, bigints, buffers, and null'
error by converting all parameters at the platform service level before they reach SQLite.
