Inconsistent error messages between get_profile and delete_profile

[anxkhn]

Context

When a profile is not found, the get_profile endpoint returns the message "Profile not found" but the delete_profile endpoint returns "User not found". Error messages should be consistent across the API for the same type of error.

Steps to reproduce

1. Request a non-existent profile:

   curl http://localhost:8000/profile/nobody

   Response: {"detail": "Profile not found"}

2. Delete a non-existent profile:

   curl -X DELETE http://localhost:8000/profile/nobody

   Response: {"detail": "User not found"}

Expected behavior

Both endpoints should use the same error message for a missing profile, e.g., "Profile not found".

Actual behavior

• GET /profile/{username} returns "Profile not found"
• DELETE /profile/{username} returns "User not found"

Files

• app/main.py -- both get_profile and delete_profile functions, specifically the HTTPException detail strings

Acceptance criteria

• Both endpoints use the same error message (e.g., "Profile not found")
• All existing tests still pass

Suggested approach

1. Open app/main.py.
2. Find delete_profile and change detail="User not found" to detail="Profile not found".
3. Run pytest tests/ -v.
