Proxy auth UI, verbose Live logs, build script, docs

- Fixed exit and manual chain: optional user/pass fields with URL merge and redaction in UI/logs
- config: split_proxy_for_edit, merge_proxy_credentials, redact_proxy_url, IPv6-style host bracketing
- Live tab: UILogHandler to stream proxy_chain_manager logs; Verbose toggle; Clear log; httpx quiet
- service/validator/fetcher: structured INFO/DEBUG for pool, GOST, validation, fetches
- setup_and_build.ps1: pip upgrade, deps, PyInstaller, desktop copy + shortcut; build_exe.bat delegates
- README: clone/pull to one-script desktop build flow
