error on accept of CCD whose parent entry dialog has been auto-closed

[caver456]

On an incoming fleetsync call for a new device, CCD is automatically raised (when that newEntryWidget is activated). If the entry stays blank and is auto-cleaned, the CCD stays open (problem #1). If that CCD is later accepted, this sequence will show up in the transcript, with two different tracebacks (problems #2 and #3):

This was found in transcript from Castle Peak May 5 2023.

Actions to take:

part 1:

• [x] close any unmodified child CCD when parent is auto-cleaned

part 2 - consider whether any of this part is necessary - maybe it's OK to close a modified CCD if its parent is auto-cleaned

• [ ] if the CCD has been modified:
  • [ ] prevent auto-cleanup of parent newEntryWidget
  • [ ] blink the parent finger tab, or some other indication that modified CCD is open (see #683)
• [ ] consider making CCD not StaysOnTop - similar handling to other child dialogs (see #683)

don't try part 2 for now, since it might be fairly invasive, would be rarely used, and is easy enough to recover from in the event that a modified CCD is auto-closed because its parent message text was blank.
