feat: add scripts for database inspection and migration

- Implemented multiple scripts to check and inspect meal plans, scraped data, and accommodations for Munich and Riga.
- Added a migration script to convert scraped data into the application's database format.
- Introduced new database service methods for querying and updating travel rates.
- Enhanced server configuration for serving static files in production.
- Updated PostCSS configuration for consistency.
