BUG: Collections returned against all Catalogs

Now ensured the list of collections within a catalog, when calling the /catalogs endpoint is cleared for each new parent catalog
Previously this meant all collections would be returned against every catalog

Username removed for user verification.
Workspaces added to the code for access control.
Workspaces obtained from STAC FastAPI routes.
Logged-in users with access to multiple workspaces:
- See all public catalogs, collections, and items.
- See other workspaces they have access to.
Users not logged in:
- Cannot access private workspaces.
- Can only view public workspaces.
Unauthenticated users:
- Cannot access any private STAC results.

Add functions to allow updating access control policies for catalogs and collections
Update function to handle parent access based on child access for catalogs and collections
Update handling of catalog deleting - removing all contained indices by wildcards
Update access control details document keys: access_control_owner and access_control_workspaces
Ensure only the owner can make changes
Update create catalogs and collections functions to create them either public or private depending on request, rather than any more fine grained access-control
