feat(notify): turn each kind of notification on or off (#7868)

SMTP settings now only decide whether mail can be sent. Verification codes, password reset, email binding and account security mails depend on SMTP alone, and no notification switch affects them. Admins get a site-wide low balance reminder switch, on by default, next to the SMTP settings. The default threshold is entered as an amount. Users choose which notifications they receive. Low balance reminders are on for everyone by default. Admins can also turn channel notifications and upstream model update notices on or off. The root user receives channel notifications until it turns them off. Other admins receive them after they turn them on. A low balance reminder is sent once, when a charge takes the balance below the threshold. A top-up above the threshold arms it again. Channel notifications reach every admin who has them on, in that admin's language. Email binding codes and account security mails follow the account's language. Saving notification settings no longer clears the language, the sidebar layout or the billing preference. Existing settings keep their behavior, and old clients that do not send the new fields keep the stored switches. Webhook, Bark and Gotify payloads are unchanged.
