Adapt email notifications to upstream APIs post-merge

- mail adapter: publish kind 30390 / DELETE subscriptions via @app/core's
  Publisher (publisher.get().publish(...).settled()) instead of the removed
  thunks API; report first failure via getError().
- push/adapters/common.ts: import writable (used by emailNotificationState).
- prettier-format the merged settings.ts + alerts page.
