feat(spec): add userActions.editInline toggle for inline record editing

Inline cell editing is a first-class, author-controlled list property, but
UserActionsConfigSchema (the shared toggle set behind both a view's toolbar
and a page's interfaceConfig.userActions) had no field for it — so the
metadata-admin "Interface (list pages)" panel, which auto-renders these
booleans as checkboxes, couldn't expose it. The runtime already honors it
(objectui InterfaceListPage reads userActions.editInline -> inlineEdit).

Add `editInline: boolean` (default false — a list is read-only unless the
author opts in), sitting alongside `addRecordForm`. When on, cells edit with
the field's type-aware widget (the same control the form uses).

view.test.ts: assert the default (false) and the accepted (true) value.
