Fixes APP-3850. Notifications v2 is now the only Notifications screen. This removes the notifications_v2:enable gate and deletes the original (v1) screen. Stacked on #12278 (compact quotes in Notifications v2).

The gate

• NotificationsScreen renders the v2 screen directly. NewNotificationsScreen is gone, and the screen's testID is now notificationsScreen. The e2e flows already used v2's IDs.
• The Beta features entry ("Redesigned notifications") and the header's beta tag are gone.
• isOnForBetaUser stays. Its test now runs against moderation_inbox:enable.

v1 code removed

• The v1 screen (view/screens/Notifications.tsx), NotificationFeed and NotificationFeedItem.
• Its feed query, state/queries/notifications/feed.ts. Post and profile shadows and the post thread placeholder now read only the grouped notifications cache.
• What only v1 used: useAnimatedValue, StarterPackCard.Notification (plus Card's noIcon/noDescription), and the v1 rows in the moderation playground. The playground keeps its v2 "every kind" section.

Unread badge

The unread poller still uses listNotifications for the badges and the Refresh pill. It used to build v1's grouped feed page so the v1 feed could reuse it as its first page. Now:

• It counts a flat list of notifications, filtered by the same moderation rules. Grouping and fetching subject posts are gone. The count is the same, since v1 counted every notification in a group anyway.
• getCachedUnreadPage, invalidateCachedUnreadPage and checkUnread({invalidate}) are gone. checkUnread is internal to the provider now, since nothing outside it called it.
• markAllRead now requires seenAt. Its fallback was the last check's sync time, and the v2 screen always passes seenAt.
• Push notifications no longer invalidate the v1 feed. Opening one still emits pushNotificationOpened, which v2 listens for.

notifications:bundleExpand keeps v1's kind names (post-like, …) so the metric stays comparable.

After merge

The notifications_v2:enable flag can be archived in GrowthBook.

Testing

• pnpm typecheck, pnpm lint and the notifications, post thread and feature tests pass.
• Not checked on a device yet.
