* feat(epg): manual EPG-to-channel mapping with mapping fallback in all EPG paths
* fix: epg mapping in live tv list
* fix(epg): harden manual EPG mapping — upgrade safety, perf, playlist-scoped keys
Follow-up fixes on top of the manual EPG-to-channel mapping feature:
- epg-database: dedupe existing epg_programs rows before creating the
unique (channel_id, start, title) index — a plain CREATE UNIQUE INDEX
crashed the EPG worker on upgrade when historical duplicates exist;
replace INSERT OR REPLACE with ON CONFLICT DO UPDATE so the
epg_programs_fts delete trigger is not bypassed (REPLACE skips delete
triggers unless recursive_triggers is on), with a plain-INSERT
fallback when the index cannot be created
- db: add idx_content_epg_channel — the mapping fallback scanned the
whole content table on every single-channel EPG lookup
- keys: scope Xtream mapping keys per playlist via shared
buildXtreamEpgMappingKey (xtream:{playlistId}:{id}) — bare stream ids
collide across portals; the backend fallback now joins categories to
resolve the playlist id
- pwa: hide "Map EPG channel" entries behind the supportsEpgMapping
capability — the menu item was a dead end in the PWA
- parser: parse the XMLTV offset sign from the string — Math.sign(0)
dropped the minutes of ±00:xx offsets
- cleanup: typed window.electron access instead of ad-hoc casts, drop
unused resolveChannelId and dialog data field, shared
EpgMappingDialogComponent.open() for all seven call sites
- dialog UX: minimum-characters search hint, save/remove snackbars,
current mapping shows the EPG channel display name,
takeUntilDestroyed on the search stream
- i18n: fill the new keys in all 17 locales
- tests: cover mapping CRUD/search escaping, the dedup-index guard,
offset parsing and playlist-scoped keys; update stale stream-resolver
specs for the new 50-item limit and 10s timeout

* fix(epg): escape backslashes in EPG channel search LIKE pattern
CodeQL js/incomplete-sanitization: a lone trailing backslash in the
search term paired with the closing wildcard under the ESCAPE clause
and corrupted the pattern.

* perf(epg): batch mapping lookups in the viewport preview queue
Expose the existing getEpgMappingsBatch operation over a new
EPG_MAPPING_GET_BATCH IPC channel and use it in resolveManualMappings —
the per-entry lookup issued one IPC round-trip per visible channel on
every scroll event.

* perf(epg): batch mapping prefetch in the collection preview loader
Resolve all candidate mapping keys for an Xtream preview batch with a
single getEpgMappingsBatch IPC call instead of per-channel lookups.
Also fix a worker early-exit: a channel without tvgId/name returned out
of the shared-iterator loop and silently killed one of the three
concurrent preview workers.

Channel-list rendering called EpgService.getCurrentProgramsForChannels(),
which forkJoined N getChannelPrograms() Observables — each firing its own
IPC round-trip and its own SQL query. For a 500-channel visible window on
first scroll, that was 500 IPC calls and 500 SELECTs hammering the EPG
table.
Add GET_CURRENT_PROGRAMS_BATCH IPC handler that takes the channel-id
array and runs a single SELECT with WHERE channel_id IN (...) AND
start <= now AND stop >= now. The renderer-side cache and TTL behavior
are preserved; only the network of IPC calls collapses to one. A
fallback path keeps the old per-channel behavior if the preload lacks
the new endpoint.
Per-channel display-name fallback (NOCASE id, then NOCASE display name)
is preserved from handleGetChannelPrograms so behavior matches the
existing single-channel handler.
