- Admin: replace Server Options dialog with per-realm management —
realms table on the overview, add/edit/delete realm dialog backed by
/auth/api/admin/realms/. Origins may be any well-formed origin;
non-subdomain ones are related origins (ROR, max 5) and the dialog
points at the .well-known/webauthn URL that must list them.
Connectivity checks compare against the edited realm's rp-id and
degrade to warnings instead of blocking saves.
- Host mode (limited profile) now keys off own_auth_host so realms
sharing another realm's auth host serve the full profile locally.
- Credential list shows a realm badge on passkeys registered for a
different rp-id than the current realm.
- Profile shows an enrollment prompt when the user has no passkey for
the current realm (e.g. after a cross-realm remote login).
- Remote auth permit shows the requesting realm when it differs from
the approver's own.
- settings cache can be force-refreshed after realm changes.
