Add RemoteRepositoryInline to ProjectAdmin to surface connected remote repository

[Copilot]

ProjectAdmin had no inline visibility into the RemoteRepository connected to a project via the remote_repository FK. Admins had no way to inspect the remote repository details without navigating away from the project page.

Changes

• readthedocs/projects/admin.py: Added RemoteRepositoryInline (read-only StackedInline) to ProjectAdmin

  • Displays full_name, clone_url, html_url, private, vcs, vcs_provider, default_branch as read-only fields
  • show_change_link = True for direct navigation to the remote repository admin page
  • No add/change/delete permissions — view-only via ReadOnlyInlineMixin
  • Collapsed by default (classes = ["collapse"])

• readthedocs/oauth/admin.py: No changes (reverted to original state)

Since Project.remote_repository is a FK from Project → RemoteRepository (not the reverse), Django's standard inline mechanism cannot be used directly in ProjectAdmin. The implementation overrides check() to skip the FK system check and overrides get_formset() to use a modelformset_factory-based formset whose queryset is built from the project's remote_repository_id:

class RemoteRepositoryInline(ReadOnlyInlineMixin, admin.StackedInline):
    model = RemoteRepository
    classes = ["collapse"]
    fields = ("full_name", "clone_url", "html_url", "private", "vcs", "vcs_provider", "default_branch")
    readonly_fields = fields

    @classmethod
    def check(cls, parent_model):
        # No FK from RemoteRepository to Project; handled manually in get_formset()
        return []

    def get_formset(self, request, obj=None, **kwargs):
        qs = RemoteRepository.objects.filter(pk=obj.remote_repository_id) if obj and obj.remote_repository_id else RemoteRepository.objects.none()
        ...

@copilot code review[agent] Do the inline the other way

Done in f82441a. The inline is now RemoteRepositoryInline inside ProjectAdmin (in projects/admin.py), showing the connected RemoteRepository when viewing a Project.

Since the FK goes Project → RemoteRepository (not the reverse), a standard Django inline isn't possible in this direction. The implementation uses a modelformset_factory-based formset that builds its queryset from obj.remote_repository_id, and overrides check() to skip the FK system check. All fields are read-only via ReadOnlyInlineMixin.
