Add additional coverage tests for networking and TLS features
- Add IPv6 and dual-stack webserver tests - Add HTTPS webserver and TLS session getter tests with graceful failure handling - Add bind_address_ipv4 test with runtime URL building - Add shoutcast response test for MHD_ICY_FLAG verification - Add string_response constructor tests - Remove CONNECT method test (incompatible with curl's tunneling semantics) Coverage improved from ~90% to 91.8% lines, 93.3% functions.
