feat(access): strict allowlist + add groups by search

* UnifiPageGrant::userCanAccess no longer falls back to "open" when a
  page has no grants saved. Pages now require an explicit grant for
  every non-super-admin user — either a direct user grant or via a
  group they belong to. Matches the new dashboard-wide access model.
* Route enforcement returns 404 (was 403) so ungranted users can't even
  confirm the page exists.
* New /settings/pages-access/groups/search endpoint mirrors the
  user typeahead. Groups are no longer all listed by default — only
  super-admin groups (locked-on) and groups with at least one existing
  grant show up in the matrix. Operators add more via search.

v1.7.1.
