feat(linkedin-search): report closed postings via isActive, wire into /scrape (adopts #280) (#383)

* feat(linkedin-search): add active status verification for job postings

* fix(linkedin-search): scope closed-posting detection to the top card, pin with tests (#280)

The first version matched five markers against the whole document, so
recruiter boilerplate quoting 'no longer accepting applications' in a
description flagged a live job CLOSED. Detection now stops where the
description markup begins and matches only the two markers real closed
pages carry (closed-job__flavor and the banner text, verified against
live guest pages); the three speculative phrases are dropped. Four new
fixture tests pin both directions plus the two description false-positive
cases - the false-positive pair fails on the unscoped version.

* feat(scrape): mark closed-at-source LinkedIn postings expired, never drop (#280)

/scrape Step 2 now consumes linkedin-search detail's isActive: a job whose
posting page renders the closed banner is written to seen_jobs.json with
status expired rather than silently dropped, per the /rank marking pattern -
the fix for the ghost-jobs class in #331. isActive: true is documented as
absence of the banner, not proof the posting is open.
