Subject: [PATCH] feat: add detailed logging for request creation errors

Backend (API):
- Added logging of user ID and request data keys before validation
- Log validation errors with full details before raising exception
- Helps diagnose 400 Bad Request errors from users

Frontend (JS):
- Added console logging of all FormData entries before submit
- Improved error message display with field-specific validation errors
- Shows structured error messages instead of generic 'HTTP 400'

This will help identify why some users get 400 errors when creating requests.
