// CRUD already built for the admin-managed mailbox pages (db.ListAppPasswordsForMailbox
// etc.), just presented for self-service instead of admin management. Only ever
// reached with MFA already satisfying enforce_mailbox_mfa (or enforcement off) —
// requireMailboxAuth redirects everywhere else, including here, to the isolated
