feat(access): per-page user/group grants, snap-in-local

A snap-in-owned access mechanism. Adds:
  - unifi_page_grants table (nav_item_id, grantee_type, grantee_id)
    with cascadeOnDelete from nav_items so uninstalling the snap-in
    wipes its grant rows automatically
  - UnifiPageGrant model + ::userCanAccess(user, navItem) helper
  - UnifiPagesAccessController (index + update), super-admin only
  - RouteMatched listener in UnifiServiceProvider that 403s any
    unifi.* route if the matched nav_item has grants and the user
    isn't a super-admin / granted user / member of a granted group

Semantics: a page with NO grants stays open per the existing
permission middleware (no behaviour change). The moment grants are
added, ONLY super-admins and listed users/groups can see/open the
page. Super-admins always pass; their access can't be removed.

v1.4.0.
