Add backend site management for collective topics and topics

- Introduced new backend site management features including the ability to accept, unaccept, save, edit, and display topics and collective topics.
- Added new views for editing and listing collective topics and topics.
- Implemented necessary backend logic in the `BackendSites` and `factory\BackendSites` classes to handle CRUD operations for topics and collective topics.
- Updated the layout to include links for accessing the new backend features based on user permissions.
