Add an EPG list view — a vertical, single-day programme list — as an
alternative rendering of the live EPG panel, selectable via a new
Settings → EPG → "Guide view" toggle (epgViewMode: 'timeline' | 'list',
default 'timeline' so existing users see no change).
- New EpgListViewComponent (app-epg-list-view) mirrors
EpgTimelineComponent's input/output contract 1:1, so all four live
hosts (M3U player, unified live tab, Xtream, Stalker) swap the panel
with a plain @if and identical bindings.
- Reuses the shared view-agnostic EPG modules (classifyTimelineWhen,
hasProgramsForDateKey, epg-archive.util catch-up gating,
epg-summary.util collapsed-summary maths, epg-date helpers,
EpgProgrammeDialogService, app-epg-timeline-empty-state) — no
duplicated logic.
- Rows show time range, title, optional description, live progress on
the on-air row, catch-up "Watch" on past rows when archive playback
is available, and a details dialog; keyboard activation guards
nested buttons (target === currentTarget).
- Auto-focuses the on-air row on channel select, restores it across
collapse/expand remounts, and shows a sticky in-flow "On now" strip
(never overlaying rows) when the current programme is scrolled away;
all scroll maths is rect-based relative to the scroller.
- List mode raises only the inline panel height via an epg--list
modifier (--epg-inline-height clamp); timeline and collapsed heights
are unchanged.
- Setting flows end-to-end (Settings interface → DEFAULT_SETTINGS →
SettingsStore/StorageMap → segmented control in the EPG section);
Electron-only UI, PWA stays on the timeline default. i18n keys added
to all 18 locales.
- Tests: new component/row/utils/scroll-controller specs, settings
persistence spec, swap tests in all four host specs, and Electron
E2E for the settings round-trip and the rendered list view. Docs
updated (m3u-playlist-module.md).

Live TV channels in Xtream playlists go blank whenever the provider's
get_short_epg returns nothing, even when the user has working XMLTV
URLs in Settings. The XMLTV pipeline already populates epg_programs
but only the M3U module was reading it.
Wire those uploads up as a fallback for Xtream too: when the provider
returns nothing for a channel with an epg_channel_id, look it up in
the local table. A settings toggle flips the priority for users whose
curated XMLTV is better than the provider's auto guide.
EpgQueueService.enqueue() became async to batch the XMLTV lookup once
per viewport change. To keep the queue consistent under fast scroll,
all shared-state mutations now happen behind a generation counter so
only the latest call commits. Per-method bridge gating in the new
XtreamXmltvFallbackService keeps each path working when the preload
exposes only one of the two endpoints.
