test(citycorners): add backend test suite (31 tests) and update documentation

Tests: Jest + ts-jest with mock factories. 4 test suites covering LocationService (CRUD, search), FavoriteService (add/remove, conflicts), LocationLookupService (web search, extraction, error handling), LocationController (endpoints, query params).

Docs: Complete CLAUDE.md rewrite with live URLs, all endpoints, web pages, features, environment variables, Docker config, and test overview.
