feat: add Troubleshooting submenu under Help (Show Logs + Open Developer Tools)

[rtibblesbot]

Plan: Add a Troubleshooting submenu under Help containing Show Logs and Open Developer Tools.

• Show Logs + Troubleshooting submenu structure
• Open Developer Tools

Summary

Adds a Troubleshooting submenu under Help containing two items that reduce support burden by giving users one-click access to debugging information:

• Show Logs — opens KOLIBRI_HOME/logs in the platform's default file manager. Extracted from the existing on_open_kolibri_home into a shared _open_in_file_manager helper.
• Open Developer Tools — opens the webview backend's developer tools window. Platform dispatch: COM vtable (ICoreWebView2::OpenDevToolsWindow) on Windows (same pattern as show_print_ui), ObjC runtime via ctypes on macOS (WKWebView _inspector), WebKitGTK ctypes on Linux. All failure paths log a warning rather than raising a user-visible dialog.

Closes #240

Reviewer guidance

Verification steps on Mac and Windows:

1. Run asset.
2. Help → Troubleshooting → Show Logs — file manager opens at $KOLIBRI_HOME/logs
3. Help → Troubleshooting → Open Developer Tools — devtools/inspector panel appears for the current page
4. File → Open Kolibri Home Folder — still works

AI usage

Implemented with Claude Code following a pre-approved plan (see issue #240). Scope and acceptance criteria were written by the maintainer before implementation.

Delete the test theater it adds nothing. We should be keeping consistent with the permission checks we already added for opening Kolibri Home - it's not clear to me if this has been branched from those changes or not.

All review feedback addressed in 1e46cba:

• Deleted tests/test_troubleshooting.py and the test machinery.
• Both Show Logs and Open Developer Tools submenu items now call .Enable(_kolibri_home_readable()), consistent with the Open Kolibri Home Folder guard.

Ready for re-review @rtibbles.

Needs more cleanup - and now we have 3 commits for what should be a single commit. Finish the cleanup and squash to one commit to remove the churn.

Hi @rtibbles,

On Windows, selecting the Help → Troubleshooting → Open Developer Tools option results in seeing the previously viewed page, like a Back button:

Windows app logs: Windows logs.zip

On Mac, selecting the Help → Troubleshooting → Open Developer Tools option results in the app crashing:
