MC-B3 correction API and review port

Status: LOCAL_DONE. Date: 2026-10-27. Base: 96952e07 plus this task. Time: ~40 minutes.

Delivered

• application.CorrectionService: validated one-field submissions, 20/day quota, one open per account+station+field, semantic idempotent replay, changed-body conflict, owner-only read/cancel, pending list and audited decisions. Validation covers location (Brazil bounds, null-island refusal), display name/brand, structured address, operating status, note/PII rejection, evidence-ref bound and coarse proximity buckets.
• Adapter CorrectionStore: generated queries, PostgreSQL unique-violation mapping, a single transaction for the decision plus its audit row, and ApplyAcceptedLocation appending a reviewed revision through the existing repository ladder (highest pin rank).
• HTTP handler with the four signed routes:
  • POST /v1/stations/{id}/corrections
  • POST /v1/stations/corrections/mine
  • POST /v1/stations/corrections/{id}/status
  • POST /v1/stations/corrections/{id}/cancel Session in the JSON body, no-store, one 404 for foreign/unknown ids.
• Composition root wires the account session validator; suspended/deleted accounts are forbidden.
• station-review operator CLI gains -corrections-list and -corrections-decide with mandatory -reason, -decider and JSON -evidence; decisions use the same port and never edit rows directly.
• OpenAPI paths and StationCorrection/StationCorrectionValue schemas added before implementation was exposed.
