"All folders" sent its Email/query only to the account of the open
folder, so mail in a shared (group) account the same login reaches never
showed up: "zephyr" found the 3 own messages and missed the 5 in the team
inbox, although that inbox sits right there in the sidebar.
The search now asks the own account and every shared account with
folders in the sidebar, like the webmail's `searchAcrossAccounts`:
- one request carries Email/query, Email/get and Thread/get for each
account (`queryEmailPagesAcrossAccounts`), and the pages are merged
under the list order
- each row is stamped with its JMAP account (`Email.jmapAccountId`), so
opening a hit opens it in that account and read, star, tag, archive,
delete, spam and move act there, filing into that account's own
Archive, Trash or Junk; one undo restores rows in every account
- "load more" continues each account from its own rows on screen rather
than one shared offset, which would skip messages of the account with
more hits
- an account that fails leaves the others' hits on screen with a notice
- a push for any account re-runs the search
- list keys, thread grouping and conversation sizes are scoped by
account, as JMAP ids are only unique per account
- deleting a hit judges Trash and Junk by the hit's own folders, not the
open folder, both for the move and for the permanent-delete confirm
A search scoped to one folder still asks only that folder's account.
