Fix notification background polling, add first/last name sharing

Notifications: enable refetchIntervalInBackground on unread count
query so notifications appear in background tabs without requiring
a tab switch to trigger refetchOnWindowFocus.

Name sharing: add share_first_name and share_last_name to the full
sharing pipeline — migration 045, Settings model/schema, SHAREABLE_FIELDS,
resolve_shared_profile, create_person_from_connection (now populates
first_name + last_name + computed display name), SharingOverrideUpdate,
frontend types and SettingsPage toggles.
