Better trash (#2190)

* Better trash

I recently lost a bunch of time editing and searching for pages that were actually in the Trash. Docmost intentionally tries to not link to Trashed pages, but the url of that Trashed page and any inbound links still work.  This makes it clearer when a page you are interacting with is in the Trash.

- /trash
  - Refactored banner into `trash-banner.tsx`
  - Refactored "Restore" modal into `use-restore-page-modal.tsx`
- Page (when isDeleted)
  - Add: `trash-banner.tsx`
  - Add breadcrumbs: `Parent / Child / Page (Deleted)`
  - Change: Deleted Pages are read-only
  - Replace "Move to Trash" with "Restore" in page menu (invokes `use-restore-page-modal`)

I tried very hard to keep this simple and re-use existing translation strings wherever possible.

* cleanup
