Adds a "subject: group:admins" rule ahead of every domain's other rules, so
admins always match first regardless of any per-service scoping (existing or
future) on that domain — a group's deny-elsewhere rule can no longer catch an
admin even if they're accidentally added to that group later.
- install_authelia and add_authelia_domain bake the rule in at creation time
- _authelia_scope_access retrofits it just-in-time before inserting its own
deny-elsewhere rule, and anchors that rule below it instead of at the top
- new menu option 13 (_authelia_ensure_admin_access_everywhere) backfills it
across every domain on an install that predates this
- remove_authelia_domain cleans the rule up too when a domain is removed,
and its domain picker dedupes since two rules now share one domain string
