Linus Rath b79781cc94 fix: never lose a draft moving between windows and keep credentials off the window channel
Review of the pop-out work found ways to lose text, a wrong sign-out and
changes reaching ordinary browser tabs.

- Drafts: a closing window hands text over only to a main window holding
  its login, and asks instead when the last save failed, the browser is
  offline, a save is running or plugins could still have a say. A failed
  rescue goes to "Continue draft". The opening window lets go only once
  the composer is on screen, also for Edit draft in a message window.
  Send options travel with the draft. Closing during a send asks first.
- Sessions: answers are encrypted for the window that asked, and only a
  window holding the login answers. A renewal queued on the lock can be
  called off by a sign-out, signs nobody out once its account is gone, and
  takes the cached token after waiting (Rauthy `nbf`, #552).
- Ordinary tabs run none of the host. No lock is held for life.
- A message window hides after a refused session and waits for its
  folders; a composer stays on screen with its text. Another tab dropping a
  login it couldn't restore no longer closes pop-outs.
- Plain-text mail stays selectable in the desktop app. Folder save renames
  reserved and shell names and skips one refused name. All display-mode
  checks know the overlay. The attachment bar keeps to one row.

The earlier test that accepted text being gone after a failed rescue now
asserts that it reaches the "Continue draft" slot.
