feat(files): add safe connector space removal

+The Files workspace exposes **Remove space** only for read-only connector
+spaces and only to actors with file-organization authority over the owning user
+or group space. Confirmation explains the exact boundary: removal soft-deletes
+the local connector-space definition and makes that virtual view disappear. It
+does not mutate or delete remote provider content, previously imported managed
+files, their metadata or shares, the connector profile, credentials, or remote
+object references. Those retained objects therefore do not block removal and
+the connector location can be linked again later. User and group managed spaces
+are intrinsic ownership scopes rather than removable records, so they never
+offer this action. A missing, already removed, cross-tenant, or inaccessible
+connector space fails through the backend lookup and owner-access checks.

 Consumers should use cursor/watermark contracts instead of assuming an
 unbounded complete list. The default full-list page size is 500 and public page
 sizes are capped at 1,000.
