Display full name in project collaborators table

[tomasMizera]

Summary: Update the Project Collaborators endpoint and UI to prioritize displaying a user’s full name over their username.

---

Backend Changes

• Endpoint: GET /v2/projects/{id}/collaborators
• Task: Add a new attribute name to the response object.
• Logic: Fetch the value using the existing UserProfile.name() method.

Frontend Changes

• Table: Project Collaborators

• Column: "Username" (or "Collaborator")

• Logic Update: Display the new name attribute if it is present and not empty.

  • Fallback: If name is null/empty, continue to display the username.

• Avatar Integration: Update the getAvatar function to use the name attribute for generating initials.

Acceptance Criteria

1. The API response for collaborators includes the name field.
2. The collaborators table shows "John Doe" instead of "jdoe123" when the full name is available.
3. User avatars generate initials based on the full name (e.g., "JD").
4. Existing functionality remains if the full name is missing.
