feat(electron): Implement SQLite database initialization with proper logging 

- Add comprehensive logging for database operations
- Implement proper database path handling and permissions
- Set up WAL journal mode and PRAGMA configurations
- Create initial database schema with tables and triggers
- Add retry logic for database operations
- Implement proper error handling and state management

Current state:
- Database initialization works in main process
- Connection creation succeeds with proper permissions
- Schema creation and table setup complete
- Logging system fully implemented
- Known issue: Property name mismatch between main process and renderer
  causing read-only mode conflicts (to be fixed in next commit)

Technical details:
- Uses WAL journal mode for better concurrency
- Implements proper file permissions checking
- Sets up foreign key constraints
- Creates tables: users, time_entries, time_goals, time_goal_entries
- Adds automatic timestamp triggers
- Implements proper connection lifecycle management

Security:
- Proper file permissions (755 for directory)
- No hardcoded credentials
- Proper error handling and logging
- Safe file path handling
