Fix nostr-client-unavailable error in ProfileModal moderation tests

Added `ensurePool` mock to `nostrClient` in `tests/ui/profile-modal-moderation-settings.test.mjs` to prevent runtime errors when `ModerationService` is instantiated.
Updated assertions to include `trustedMuteHideThresholds` as it is present in the default settings snapshot.
