ref(ui): deprecate useProjects() without slugs

[dcramer]

Add a development-time console warning when useProjects() is called without the slugs parameter. This prepares for removing the all_projects=1 bootstrap fetch by encouraging explicit project fetching.

Updates 18 components to pass specific slugs to useProjects(), ensuring they will continue working when projects are no longer pre-loaded.
