🧹 Remove unused legacy modules and functions

- Deleted quota.rs module (quota management not needed via HTTP)
- Removed legacy get_id_by_token GraphQL function
- Removed unused set_user_quota and increase_user_quota methods
- Cleaned up unused imports and legacy structs
- Simplified handlers/mod.rs to only expose universal_handler

Architecture now focused on core functionality:
- GET / (user info)
- GET /<filename> (file serving)
- POST / (file upload)
