Fix MySQL support and TUI auto-confirm mode

- Fix format detection to read database_type from .meta.json metadata file
- Add ensureMySQLDatabaseExists() for MySQL/MariaDB database creation
- Route database creation to correct implementation based on db type
- Add TUI auto-forward in auto-confirm mode (no input required for debugging)
- All TUI components now exit automatically when --auto-confirm is set
- Fix status view to skip loading in auto-confirm mode
