Email reader: regroup More menu + reshuffle toolbar rows

More menu reorganization:
- Group 1: Open in new tab, Remind to reply
- Group 2 (state): Mark as Unread/Read, Mark as Done/Not Done, Move to
  Archive, Save sender to contacts
- Group 3 (destructive, unchanged): Move to Spam, Move to Trash,
  Delete Permanently
- Renames: Done→'Mark as Done', Archive→'Move to Archive', Mark
  Read/Unread→'Mark as Read'/'Mark as Unread'.
- Mark Unread moves out of group 1 down into the state-change group
  alongside Done; Save sender to contacts moves down into the same
  state group.

Toolbar row reshuffle (applies to both the email-list card reader and
the email document view):
- Row 1 (primary): Reply, Reply all, Forward, Search, More — Forward
  no longer has to fight Search/More for space in the secondary row.
- Row 2 (secondary): AI reply, Summary — gets its own dedicated row.
