Two fixes via one workspace command: 1. Gates 5 standard command menu items behind `pageType == "INDEX_PAGE"` -- `importRecords`, `exportView`, `seeDeletedRecords`, `createNewView`, `hideDeletedRecords`. They currently appear (and crash or do nothing) on RECORD_PAGE. 2. Fixes Edit Layout missing from older workspaces -- root cause is `conditionalAvailabilityExpression` drift between source-of-truth constants and the workspace DB (e.g. #20556 removed a feature flag from the expression without syncing existing workspaces). The 2-6 workspace command iterates all `STANDARD_COMMAND_MENU_ITEMS` and reconciles any `conditionalAvailabilityExpression` that differs from the constant. Idempotent -- already-correct rows are skipped. Deferred: `deleteRecords` doesn't refetch the current record after deletion on RECORD_PAGE (mutation fires but UI shows stale state until refresh) -- different fix shape (frontend handler), separate PR.
