New Settings → Notifications section with a toggle per category (follow, comment, reply, reaction, rating, mention, leftover-expiring, shared shopping list) — previously it was all-or-nothing (browser permission only). userNotificationPrefs (one row per user, defaults all-on so existing users see no behavior change until they opt out of something). Gated the push send in the three places that dispatch one: lib/notifications.ts (the 6 in-app notification types), the leftover-expiry cron, and shopping-list-notify — in-app notification-center entries and email are unaffected, this only gates the push itself, matching the literal ask. Verified locally: GET/PUT round-trips correctly, disabling a category and confirming the settings page renders all 8 toggles.
