Previously, if the Gst/GstApp/Cogl GI typelibs couldn't be loaded (e.g. gst-plugins-base/good not installed, only the bare gstreamer package), the only sign was a warning buried in the shell's log — the live wallpaper page looked fully functional and silently did nothing. Preferences now probes for the same bindings the running extension needs and shows a warning row with the exact import error plus per-distro install commands, and greys out the controls that only matter once GStreamer is actually available. Extracted the shared probing logic into lib/gstreamerAvailability.js so extension.js and prefs.js (separate processes) don't duplicate it.
