| - Broadcast notifications now have per-user read/archived state to prevent cross-user state leaks. Previously, when one user marked a broadcast notification as read or archived it, it affected all users' inboxes. Now each user's read/archived status is tracked independently in the `notification_user_state` table, preserving individual inbox states while maintaining the shared broadcast nature of the notification.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Exclude broadcasts archived by the current user from the active list.
archive() stores a broadcast archive in nus.archived_at and leaves n.archived as 0. This query only filters n.archived, so an archived broadcast remains in list() and also appears in list_archived().
Add a nus.archived_at IS NULL condition for broadcast rows.

Alias notifications as n in the user-scoped unread query.
The JOIN and WHERE clauses reference n.id and n.user_id, but FROM notifications does not define n. Every unread_count(user_id=...) call fails with a SQLite column error.

Preserve the other per-user state field during upserts.
INSERT OR REPLACE deletes the conflicting row before inserting the replacement. Marking a read broadcast as archived clears read_at. Marking an archived broadcast as read clears archived_at and makes it active again.

Do not update shared broadcast rows in mark_all_read(user_id=...).
The user_id IS NULL condition matches broadcasts and changes their shared notifications.read value. Users without a notification_user_state row then see those broadcasts as read.
Update notifications.read only for user-specific rows. Upsert read_at for the current user's active broadcasts while preserving existing state fields such as archived_at.
