fix(mothership): restore integrations to useAvailableResources for @ mention

Integrations were fully removed from useAvailableResources which broke
the @ mention menu since user-input shares the same hook. Now integrations
are always included in the hook but excluded at the AddResourceDropdown
component level, keeping them out of the sidebar + menu while remaining
available for @ mention autocomplete.
