BoulderBadgeDad 0cf8654f47 Smart scan: poll the probe over a grace window (server auto-scan needs ~1-2 min)
The probe fired the instant a batch finished, but a fresh drop takes ~1-2 min to
appear even with the server's auto-scan ON — so it always missed and we crawled
anyway, defeating the optimization. Now probe_present_libraries POLLS each candidate
over a grace window (probe_grace_minutes, default 2), skipping a library's crawl as
soon as the server reports it has the item, and only crawling what's still missing
when grace expires. The probe target for a media type you DIDN'T just download is an
old item the server already has → confirmed instantly, no wait. grace=0 probes once.

"""Seam-level tests for the ``video_scan_library`` automation handler.
The handler is the VIDEO twin of ``scan_library``: it nudges the media
server to rescan the user's selected video sections, then reads the result
into video.db. Both side effects are injected (``server_refresh`` /
``run_video_scan``) so these tests exercise the real handler logic with
fakes — no Flask, no DB, no media server.
