UK ERL Validation: Support Geocoordinates for Non-Postal Locations
Problem: Current UK Emergency Response Location (ERL) validation strictly requires a "Premise" match in the Royal Mail database (via SmartyStreets). Valid physical locations that lack residential postal data (e.g., Maritime Lifeboat Stations, remote utility substations) are currently rejected, blocking safety compliance for enterprise customers.
Use Case: RNLI (Royal National Lifeboat Institution) cannot register active Lifeboat Stations for 999 services because these facilities are not in the Royal Mail delivery database, despite having physical locations. (Reference Case: #29897714).
Proposed Solution: Allow Latitude/Longitude coordinates to be accepted as valid ERL metadata when a standard postal address cannot be validated.
Business Impact: Unblocks onboarding for customers with critical infrastructure in maritime, industrial, or rural zones where postal addresses are non-existent or low-precision.
