feat: suppress console spam for expected HTTP errors in profile operations

- Change server switching logs from info to debug level
- Implement structured error logging for profile CRUD operations
- Handle HTTP status codes 400, 401, 403, 404, 409 gracefully
- Suppress full error stack traces for expected API responses
- Maintain user notifications while improving console readability
- Add timestamp and context to all profile-related error logs

Improves developer experience by reducing console noise while preserving
debugging information and user-facing error handling.
