[BUG] Add missing imports for encrypt, PlatformCredential, and resolve_user_credentials in main.py

[Aditi-Singh-14]

Description

backend/main.py uses three symbols that are defined in other modules but never imported:

• encrypt from backend/utils/crypto.py
• PlatformCredential from backend/models/user.py
• resolve_user_credentials from backend/services/credential_service.py

This will cause a NameError at runtime when any endpoint that uses these symbols is called.

Steps To Reproduce

1. Start the backend server
2. Hit /generate-blog or /auth/linkedin/callback endpoint
3. Observe NameError: name 'resolve_user_credentials' is not defined

Expected Behavior

All symbols should be properly imported at the top of main.py.

Hi @vanshaggarwal27 ,
after syncing with the latest upstream, all three symbols: encrypt, PlatformCredential, and resolve_user_credentials are already properly imported in main.py.
This issue has been resolved and can be closed.
