Move the EpcClientService package (client + _retry + exceptions + tests) from the dying backend/ tree to infrastructure/epc_client/ as the New-EPC-API Fetcher; update the two callers (address2UPRN, a script). All 14 client tests pass. Add SolarRepository port + SolarPostgresRepository persisting Google Solar building insights as JSONB (solar_building_insights table), one row per Property. The EPC repo half of this slice already landed in #1129. pyright strict clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
