[PM-8004] [AC-2603] [AC-2616] [AC-2621] [AC-2622] Unmanaged collection fixes (#9301)

* [AC-2603] Add unmanaged property to CollectionAdminView and response models

* [AC-2603] Cleanup CollectionViews

- Remove getters that have been replaced with Unmanaged property
- Remove AddAccess that is also being replaced
- Add canEditUnmanagedCollections() helper to organization

* [AC-2603] Replace old AddAccess logic with Unmanaged flag

* [AC-2603] Fix failing test

* [AC-2603] Ensure Add Access badge/toggle only shows when V1 flag is enabled

* [AC-2603] Undo change to canEditUserAccess and canEditGroupAccess

Custom users should not get access to an unmanaged collection with only Manage Groups and Manage User permissions. That is still reserved for admin/owners and EditAnyCollection custom users.
