git_ui: Fix tooltip overlaying context menu in git blame (#42764)

Closes #26949


## Summary

1. Split editor references to avoid borrow conflicts in event handlers
2. Check
[has_mouse_context_menu()](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html)
state directly in tooltip conditional instead of caching stale value
3. Restructured context menu deployment to ensure proper sequencing:
hide popover → build menu → deploy menu → notify for re-render

Release Notes:

- Fixed an issue where the context menu in the Git Blame view would be
frequently overlapped by the commit information tooltip.
