fix(sqlite): Standardize connection options and improve error handling

Changes to sqlite-init.ts:
- Standardized connection options format between main and renderer processes
- Added explicit mode: 'rwc' to force read-write-create mode
- Added connection registration verification
- Added detailed logging of actual file paths
- Added journal mode verification to detect read-only state
- Removed redundant PRAGMA settings (now handled in main process)
- Added more detailed error reporting for connection failures

Security:
- Ensures consistent read-write permissions across processes
- Verifies database is not opened in read-only mode
- Maintains proper file permissions (644) and directory permissions (755)

Testing:
- Verified connection creation in both main and renderer processes
- Confirmed journal mode is set correctly
- Validated connection registration
- Tested error handling for invalid states
