The `tickets` schema (INC/CRQ map), its migrations, and the ingest/geocode loader
moved to their own repo: repo.rahamafresh.com/kianiadee/fleettickets.git.
- remove migrations 21-23 and tools/import_tickets.py
- run_migrations.py: drop the 21-23 entries (fleettickets owns them now)
- dashboard_api keeps GET /webhook/tickets, calling reporting.fn_tickets_for_map
which fleettickets defines
- move geocoder env-var docs to fleettickets
