refactor: remove upload and web-api routes, migrate to new controller structure

- Deleted `upload.ts` and `web-api.ts` routes, consolidating logic into dedicated controllers.
- Updated import paths in tests to reflect new controller structure.
- Refactored Telegram API utilities to utilize a bot pool for improved bot management and error handling.
- Enhanced environment variable tests to ensure additional bot tokens are correctly populated.
- Adjusted S3 bucket configuration tests to align with new controller imports.
- Updated Telegram queue implementation to reflect new infrastructure organization.
