4grayandClaude Opus 4.7 d1af5f0510 perf(epg): batch current-programs lookup into a single IPC + SQL query ...

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.

Inspired by matracey/iptvnator@d25a7e8.
