Folder subscriptions are the reader's own and they have none in an
account handed to them, so only Inbox showed. Every folder shows while a
locked account is in view, and Hide from list is gone there.
When the server hands a locked account to the reader (urn:inbuxa:jmap
delegation), the account popover offers it. Only mail follows the switch;
the reader's own settings, push and notifications stay theirs. A red bar,
a red wordmark with a padlock and the tab title say which account is in
view. Read delegates can't change anything, organize delegates can't
delete, and writing needs send-as. A delegation taken away drops back to
the reader's own mail.
14 new strings in all nine catalogs, unreviewed (inbuxa AL-7, AL-8).
