Remove leftovers before a release

- gaze/tracker/lab/eyes_track.py: nothing used it
- Input Settings: the pointer role backend, whose page was removed
- ft-screens: no log line for every floating-window resize
- hands: ft-hands --help gives the palm-down default (1: off), the
  uninstall removes ft-handsctl's link, .frame-job is ignored
- Display Settings: "Save as profile…", not "Save current arrangement"
- two stale comments (ft-pointer's grabprobe, ft-gaze)
