refactor: deduplicate URL generation and standardize on localhost

Browse source 
- Extract duplicated URL generation code into getClientUrl() helper function in start.js
- Replace all 127.0.0.1 references with localhost for consistency across codebase
- Update server to respect HOST environment variable for URL generation
- Remove 127.0.0.1 from default allowed origins in CORS configuration
- Update documentation to use localhost instead of 127.0.0.1
