Feature request: wider mouse support in the TUI

[pshickeydev]

The recent update with mouse support for Questions is particularly helpful in herdr sessions where I am already using my mouse. When a Permission Required modal pops up I often instinctively try to click it.

This seemed like a reasonable entrypoint to the code base so I forked and started work on this before fully searching open PRs. It looks like for Permission Required this is implemented in #2527 and wider support is planned in #3100 .

Since I started my session based on aligning to Question behavior I have logic for hover highlighting and some test cases which may still be useful. Just let me know and I'm more than happy to contribute what I can.
