Ajay - Fix Project WBS list and Tab Preview Names

[AJAYINAVOLU]

Description

This PR fixes the Project WBS List caused by the .container (src\components\Collaboration\Collaboration.css). After merging collaboration.css, the global .container class applied align-items: center, causing layout compression in the project WBS list view. Added style={{ alignItems: 'normal' }} to the <div className="container pt-2"> to override the conflicting CSS and restore proper alignment.
Replaced titles containing fullName with generic names (User Profile, Edit User Profile) to avoid displaying "Default User" in cases where authUser fails to load. This ensures a consistent user experience regardless of authentication state.
