Clicking a new-mail notification opened `/mail/message/<id>` in
whichever account was active. With several accounts signed in, that
looked the id up in the wrong account: nothing opened, or a different
message did and was marked read.
The preview API now returns the cookie slot of the login that owns the
notified account, the service worker adds it to the permalink (or links
that account's Inbox for a group notification), and the app switches to
the login on that slot before opening the message.
Resolve the Inbox mailbox id before running Email/query.
The previous query passed a JMAP result reference object directly into the inMailbox filter, which can make the preview endpoint return 502 and cause push notifications to fall back to the generic “New mail” text.
