Fix hybrid extraction skipping archives when item status stuck

Add disk-fallback to findReadyArchiveSets: when all archive parts
physically exist on disk with non-zero size and none are actively
downloading/validating, consider the archive ready for extraction.
This fixes episodes being skipped when a download item's status
was not updated to "completed" despite the file being fully written.

Also improve debug server: raise log limit to 10000 lines,
add grep filter, add /session endpoint for raw session data.
