🗑️ chore: Remove Deprecated Project Model and Associated Fields (#11773)

* chore: remove projects and projectIds usage

* chore: empty line linting

* chore: remove isCollaborative property across agent models and related tests

- Removed the isCollaborative property from agent models, controllers, and tests, as it is deprecated in favor of ACL permissions.
- Updated related validation schemas and data provider types to reflect this change.
- Ensured all references to isCollaborative were stripped from the codebase to maintain consistency and clarity.
