Extract geocoding functions into shared api/inc/geocode.cfm and call
geocodeAddressById() via cfthread after every address INSERT or UPDATE.
Uses OpenStreetMap Nominatim (free, no API key). Non-blocking — the
HTTP call runs in a background thread so responses aren't delayed.
Affected endpoints:
- setup/saveWizard.cfm (new business creation)
- businesses/update.cfm (business address update)
- portal/updateSettings.cfm (portal settings save)
- addresses/add.cfm (customer delivery address)
