fix(mail): drop contacts from the EAS bundle — Stalwart 404s empty addressbook homes

BackendCombined login is all-or-nothing, and Stalwart returns 404 for
/dav/card/<account>/ when the account's default address book was never
created (it doesn't auto-create on the gateway's PROPFIND the way the
calendar home worked) — so CardDAV killed every otherwise-successful
EAS login. Exchange accounts now bundle mail + calendar; contacts stay
on the Apple-profile CardDAV path. Re-enable BackendCardDAV once
platform-api provisions a default address book at mailbox creation.
