- Introduced a new endpoint `GET /teams/:team_id/members/:member_id/profile` to allow users to retrieve member profile information, including display name, bio, avatar, and email.
- Implemented the `GinMemberGetProfile` handler to process profile retrieval requests with appropriate authentication and error handling.
- Added business logic in `memberGetProfile` to ensure only authenticated users can access their own profile data.
- Expanded test cases in `TestMemberProfileGet` to validate various scenarios for profile retrieval, ensuring comprehensive coverage for authentication and data validation.
