fix(tables): don't show the update-lock notice to users without write access

Double-click checked the update lock before any permission check, so a
read-only member on a locked table got "Editing rows is locked" — misleading
(the lock isn't why they can't edit) and it swallowed the expanded-cell
viewer, which is a legitimate read-only affordance.
