Qt: migration to 6.6.1

This commit makes the necessary changes to migrate from Qt 6.5.3 to
Qt 6.6.1 and fixes the following issues:

- EditedPopup.qml: "layout polish loop" and "recursive rearrange"
  errors (GitLab: #1510) as well as an unreported bug where text was
  clipped instead of elided

- BaseContextMenu.qml: QML warning ("Created graphical object was not
  placed in the graphics scene.")

The daemon is also bumped in order to include a patch for a build issue
on openSUSE Leap (GitLab: #1552).

GitLab: #1466
