Enhance error handling in PeerPortchecker and TorManager; update Open…

[MudDev]

This pull request improves error handling and bundled path detection for several platform-dependent features, especially when running as a PyInstaller executable on Windows. The most important changes include robust extraction of data from external service responses, improved handling of bundled binaries, and better authentication fallback logic.

Error handling improvements for external service responses:

• Added explicit checks for missing regex matches in PeerPortchecker.py methods (checkCanyouseeme, checkIpfingerprints, checkMyaddr, checkIpv6scanner), raising exceptions with clear messages when expected data is not found. This prevents crashes due to unexpected response formats and makes debugging easier. [1] [2] [3] [4]

Bundled path detection and platform support:

• Updated TorManager.py to detect if running as a PyInstaller executable and correctly set the path for tor.exe and meek-client.exe, improving compatibility for bundled Windows builds.
• Enhanced OpensslFindPatch.py to check for OpenSSL DLLs in the PyInstaller _MEIPASS directory as well as the current working directory, ensuring the application finds required libraries regardless of installation method.

Authentication fallback logic:

• Improved Tor controller authentication in TorManager.py by catching file access errors for the cookie file and attempting empty authentication if the cookie is unavailable. This increases robustness when running with external Tor instances or on different platforms.
