Admin Patch Intake Source

Operator repair for a single IntakeSource.

default_vertical exists because prod runs INTAKE_PRIORITY_VERTICALS_ONLY=1: a source whose vertical is NULL or not a PODCAST_VERTICAL_META key has EVERY article silently skipped (app.intake.worker._passes_priority_vertical). Such a row is indistinguishable from a healthy one — active, polled on schedule, last_error NULL — while producing nothing, for as long as nobody notices. Onboard has derived a valid vertical since 2026-07-16 and repair_active_source_verticals can sweep the backlog, but there was no way to fix ONE named source without a shell inside the VPC. That gap is why a live publisher's feed sat active and empty for 23 days.

show_name is the per-source title — the same field the publisher-facing rename writes.
