Each clip row in the adult collection detail view now shows its runtime, and
the header shows total runtime of the queued set (for planning a session of a
given length). Durations are probed in one background SSH batch via ffprobe on
black (NUL-delimited paths over stdin, so the eporner filenames with spaces/
quotes/brackets pass verbatim), debounced on filter and capped at 400 per batch.
