feat(politics): add new political office benefits and enhance database migration

- Introduced new benefits including 'reputation_periodic', 'appoint_politicians', 'set_regional_tax', 'free_lover_slots', 'guard_protection', and 'court_immunity' to the political office system.
- Updated database migration to add and remove the 'last_political_daily_salary_on' column using SQL queries for better performance.
- Enhanced localization files for multiple languages to support new benefits, improving user experience across the application.
- Updated UI components to display new benefits correctly in the PoliticsView, ensuring accurate representation of political office functionalities.
