Link command menu items to specific page layout (#19706)

- Add a `pageLayoutId` foreign key to `CommandMenuItem`, allowing
command menu items to be scoped to a specific page layout instead of
being globally available
- Filter command menu items by the current page layout on the frontend.
Items with a `pageLayoutId` only appear when viewing that layout, while
items without one remain globally visible
- Create an effect to track the current page layout ID
- Include a seed example: a "Show Notification" command pinned to the
Star history standalone page layout
