feat: add content filter to home FilterSearchbar with EE-gated content view

- Clear the kind filter by deleting the key (was showing a 'kind: null' tag on All)
- Remove the standalone Content button
- Add a 'content' filter; when set, render the Ctrl-K content-search view
  (ContentSearchInner) which shows text-match snippets and its own EE warning
