fix(epg): offer the Guide action in the list view too

The EPG list view mirrors the timeline's input/output contract, but the Guide
action was bound only in the timeline branch, so Settings → EPG → Guide view =
List lost the in-panel entry point. The list toolbar now carries the same
icon-only Guide button behind `guideAvailable`/`openGuide`, and the M3U
host binds it in both branches.
