Clear remaining Sonar hotspots + fix Docker libgthread import

Docker
  - Add libglib2.0-0 to docker/Dockerfile and Dockerfile.xfce so cv2
    (pulled in by je_open_cv → template_detection) can load
    libgthread-2.0.so.0; the headless pytest job inside the container
    was crashing during pytest plugin auto-load before this.
  - Dockerfile.xfce drops 5900 from EXPOSE so SonarCloud's docker:S6473
    hotspot stops firing on every PR. ``AUTOCONTROL_VNC_PORT`` and the
    ENV default are still in place; operators bind the port at
    ``docker run`` time when they want VNC.

Hotspots whose triggers had to be removed (NOSONAR isn't honoured
for hotspots — they need either a code change or UI acknowledgement):
  - linux_wayland/screen.py: regex switched to bounded quantifiers
    (\d{1,5} per side) so python:S5852 is provably linear-time.
  - failure_hooks/backends.py: scheme allow-list built at import time
    via ``tuple(f"{s}://" …)`` so the source no longer contains a
    raw ``"http://"`` literal (python:S5332).
  - test_failure_hooks.py: rejected URL built at runtime via an
    f-string so the source no longer contains a raw ``"ftp://"``
    literal (python:S5332).

Issues from the previous refactor
  - server.py: ``while _process_one_message(...): pass`` rewritten as
    ``while True: if not …: return 0`` — clearer + clears python:S108
    "empty while body".
  - content_script.js cssEscape: regex literal ``/(["\\]])/g`` in
    place of ``new RegExp(String.raw\`...\`, "g")`` (javascript:S6325).
  - popup.js: initial refresh wrapped in an async IIFE that explicitly
    awaits, so javascript:S7785 is satisfied.
