Subject: [PATCH] fix(notification): make security-critical mails
 non-suppressible (#3850)

* chore: remove legacy Azure DEV workflow (DEV now runs on dfxdev)

* fix(notification): make security-critical mails non-suppressible

ACCOUNT_MERGE_REQUEST, CHANGED_MAIL, ADDED_ADDRESS and ACCOUNT_DEACTIVATION
were mapped to MailContextType.INFO, causing them to be silently dropped for
users whose wallet disables the Info mail type. These are mandatory
account-blocking or security notifications and must always be delivered.

Maps them to null (same as MONITORING/WEBHOOK/SEPA) so isDisabledMailWallet
short-circuits and the mails bypass wallet mailConfig checks entirely.

Closes #3842
