Add Windows PyInstaller build workflow, UI automation improvements, and diagnostics

[sircharlo]

Motivation

• Enable automated compilation of the Python ZoomMate app into a Windows executable and improve UI automation reliability for Zoom controls.
• Replace many no-op stubs with real interactions using the automation backend and UI path diagnostics to better detect and toggle Zoom UI elements.

Description

• Add a GitHub Actions workflow /.github/workflows/compile-python.yml that runs on Windows, installs dependencies, builds a single-file executable with PyInstaller, verifies the artifact, uploads it, and can commit the compiled exe on push.
• Add runtime dependencies to pyproject.toml for pyautogui and pywinauto.
• Implement real Zoom UI behaviors in pyzoommate/automation/meeting_automation.py, including _SnapZoomWindowToSide, SetSecuritySetting, MuteAll, ToggleFeed, PulseSpotlightHostVideo, EnsureGalleryView, and tighter launch/pre/post meeting flows, all using the _AUTOMATION_BACKEND and user settings.
• Add UI path diagnostics and resolution helpers in pyzoommate/diagnostics/path_wizard.py, including ResolveSecurityToggle, improved Ensure* checks, path error tracking, and enhanced RunUIDiagnostics.
• Improve state profiling in pyzoommate/diagnostics/state_profiler.py by detecting the participants panel via _FindParticipantsPanelInternal.
• Make i18n file loading robust inside PyInstaller bundles by detecting sys._MEIPASS in pyzoommate/i18n/__init__.py.
• Update scripts/build_exe.ps1 to include the Includes directory in the PyInstaller bundle.

Testing

• No automated tests were executed as part of this change; a CI job (compile) was added to build the Windows executable but was not run within this PR.
