Mail & notifications

Mail (togo-framework/mail): a Mailer with SMTP (default) + log drivers; Resend via togo-framework/mail-resend (MAIL_DRIVER=resend). SES works through SMTP.

Notifications (togo-framework/notifications): Laravel-style channels — mail, broadcast (realtime), database, and push providers (OneSignal via togo-framework/notifications-onesignal; FCM/Pusher follow the same pattern).
