feat(spec): interfaceConfig.recordAction — configure how a list opens a record

Adds `recordAction: 'drawer' | 'page' | 'modal' | 'none'` to InterfacePageConfig
and a select for it in the page form (under User actions). Lets the author choose
how clicking a record opens its detail — right-side drawer (default), full-page
navigate, modal, or not clickable.

Pairs with the objectui runtime (InterfaceListPage wires the click → drawer /
navigate / overlay accordingly).
