0.6.13: Fix watermark maintenance jobs, honest buy-link write reporting, Qobuz 403 diagnosis

scrub-watermark-text.py crashed on every run (missing import os). strip-watermark-art.py
was starved every Sunday by lock contention from strip-mb-tags' growing runtime -- moved
it to 01:00 so the rest of the weekly chain has room. enrich-buy-url.py's summary line
counted matches found, not successful writes, so a run where every metaflac write failed
(root-owned files) still reported "N tagged". pipeline-status.sh now tells a 403 from
Qobuz (Akamai/CDN block) apart from a 401 (actually expired token) -- re-exporting the
token does nothing for the former. Also fixes the dedup review table's "Caught by" badge
overflowing into the Keep column's format pill.
