fix(proxy): improve global proxy stability and error handling
- Fix RwLock silent failures with explicit error propagation - Handle init() duplicate calls gracefully with warning log - Align fallback client config with build_client settings - Make scan_local_proxies async to avoid UI blocking - Add mixed mode support for Clash 7890 port (http+socks5) - Use multiple test targets for better proxy connectivity test - Clear invalid proxy config on init failure - Restore timeout constraints in usage_script - Fix mask_url output for URLs without port - Add structured error codes [GP-001 to GP-009]
