Settle the suite-wide fallout of the wave

- The record-settings contract, slug-list, and section-frame tests
  follow the slugs that left the registry (layout children resolve
  their headings from the layout namespace, like production).
- The orphaned settings.sections.<module>.title/description keys leave
  all six locales; the reverse-coverage guard flagged them the moment
  their nav entries stopped existing.
- The operator-cap ledger read fails open on a read error — the
  reservation layer still meters against the same ledger, and a
  transient blip must not take the fallback chain down.
- The reaper queue joins the subsystem surface; its healed count and
  the sweep's nag_dismissed join the job-fact vocabulary.
- The intake-event contract fixture carries the full row the resource
  now declares; the workouts empty-state test asserts the
  source-neutral cue; the persister poll gates on rendered content
  first.
