"Continue rebase" confirmation popup not dismissed when rebase is completed externally

[aofei]

Describe the bug

When a rebase has conflicts and the user resolves them and runs git rebase --continue in an external terminal, the All merge conflicts resolved. Continue the rebase? confirmation popup remains visible even though the rebase has already completed. The Files panel correctly refreshes and shows no conflicting files, but the popup stays on screen.

To Reproduce

1. Start a rebase that results in conflicts
2. Resolve the conflicts manually in an external editor
3. Run git add <file> and git rebase --continue in a separate terminal
4. Lazygit detects conflicts are resolved and shows the Continue popup
5. The popup remains visible even though the rebase has already completed

Expected behavior

The confirmation popup should be automatically dismissed when the rebase/merge is no longer in progress.
