Show relay in edit-permission screen; add relay scope to multi-event screens

EditPermission / PermissionRow:
- Kind 22242 permissions now show their relay below the main label.
  Wildcard "*" displays "All relays"; a specific URL is shown as-is.

BunkerMultiEventHomeScreen / IntentMultiEventHomeScreen:
- When a batch contains kind 22242 relay-auth events an
  "Authentication scope" toggle appears (same as the single-event
  BunkerRelayAuthScreen): "This relay only" vs "All relays".
- The selected scope is applied to every kind 22242 event in both the
  approve-all and discard-all flows.
