[Bug]: occ user:profile <uid> email updates only the account property, leaving the system email address (IUser::getEMailAddress) unchanged

[nursoda]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

user:profile writes only the account property via IAccountManager::updateAccount() (core/Command/User/Profile.php, editProfileProperty()/deleteProfileProperty()). Neither Profile.php nor AccountManager call IUser::setEMailAddress(), so the preference settings/email keeps its old value. Consequences:

• The users page and the profile show no email address, but IUser::getEMailAddress() still returns the old one — emails (activity mails, two-factor email codes, …) keep going to the supposedly deleted address.
• UserChangedEvent for eMailAddress is never fired, so apps reacting to email changes (e.g. the twofactor_email provider disabling itself when the address is removed) do not notice.

Suggested fix

Special-case the email key in user:profile and route it through IUser::setEMailAddress() — exactly like user:setting already does for settings email (core/Command/User/Setting.php). The existing sync hook then updates the account property and the proper events fire.

I am happy to provide a PR using Claude Code if this direction is agreed.

Steps to reproduce

1. Give a user a primary email address, e.g. occ user:setting alice settings email alice@example.com (or via the users page)
2. Run occ user:profile alice email --delete (setting a new value shows the same problem)
3. Compare occ user:profile alice email (empty) with occ user:setting alice settings email (still returns the old address)

Expected behavior

The email address is changed consistently, like the personal settings UI, the provisioning API, and occ user:setting alice settings email do: account/profile data and the system email address (IUser::getEMailAddress()) stay in sync, and OCP\User\Events\UserChangedEvent (feature eMailAddress) is fired.
