v0.1.7: delete companies for re-evaluation

- DELETE /api/companies/{slug}: wipes the ledger (deck records, scorecard,
  report md), sweeps per-job report and processed-deck copies; optional
  restore_decks moves the graded originals from /data/processed back into
  the inbox for a fresh Grade Decks run; 409 while a job is running;
  config-registered companies reappear as empty rows (aliases + pinned
  targets kept)
- Dashboard: "delete company…" danger button on the company card with a
  two-step confirm (delete, then restore-decks choice)
