v0.4.9

Fixed

• Conversion failing with Invalid UTF-8 in decoded subtitles text on whole series with non-English / older releases. Root cause: when merge_external_subs was enabled and the folder had a sidecar .srt file, the converter mapped it as a separate ffmpeg input AND used -c:s srt to re-encode it — forcing a decode→encode roundtrip through ffmpeg's strict UTF-8 SRT encoder. SRT files in the wild are frequently Windows-1252 / ISO-8859-1, which fail the UTF-8 validator and abort the entire encode with exit code 69 (Conversion failed!). Fix: byte-copy SRT/ASS/SSA external subs (-c:s copy) instead of re-encoding. Both backend/converter.py and backend/audio.py had the same bug; both fixed. Most MKV players handle non-UTF-8 SRT via charset auto-detection, so the byte-copy result is more compatible than what the re-encode would have produced anyway.
• Failed jobs not showing the ffmpeg command + log in the new collapsible sections that v0.4.8 added. Backend bug: the converter's failure return paths only included error (the short message) — ffmpeg_command and ffmpeg_log weren't included on failure, so the worker never wrote them to the DB. Frontend dutifully looked for fields that were always null. Fix: failure returns now include both fields, and the worker calls update_conversion_log on failure (with encoding_stats=None) parallel to the success path.
