fix: notify on NIP-34 pull requests (kind 1618/1619)

New pull request events (GitPullRequestEvent, kind 1618) and pull
request updates (GitPullRequestUpdateEvent, kind 1619) were never wired
into the notification pipeline, which only handled patches (1617) and
issues (1621). As a result repo maintainers received no notification
when a PR was opened against their repository, even though the PR event
p-tags the repo owner.

Add both kinds in all four places that gate notifications:

- FilterNotificationsToPubkey: request the kinds from relays so the
  notification subscription actually pulls PR events.
- NotificationFeedFilter.NOTIFICATION_KINDS: let cached PR events through
  to the in-app Notifications tab.
- NotificationFeedFilter.tagsAnEventByUser: treat PR/PR-update as
  notifiable (mirrors the existing patch/issue handling).
- EventNotificationConsumer: dispatch PR/PR-update via notifyMention so
  push notifications fire.
