feat: initial scaffold for Rock Cosmetics Adit ingestion (#1784)

- pyproject.toml with rock-ingest CLI entrypoint
- config, db, ingest, migrate modules mirroring agency-marketing-ingest patterns
- column_map.py with stubbed COLUMN_MAP — fill once Adit CSV export lands
- 3 SQL migrations: schema bootstrap, imports tracking, leads table with GHL match_status
- drop/ directory for Adit export files (CSV first, xlsx fallback)
- GHL_CLINIC_NUM TBD pending Sir Alex Therrien confirmation

+Export preference: CSV > xls/xlsx > PDF (last resort).
