This PR improves how we display markdown tables by relying on grids
rather than flexbox. Given this makes text inside each cell wrap, I
ended up removing the `table_overflow_x_scroll` method, as it was 1)
used only in the agent panel, and 2) arguably not the best approach as a
whole, because as soon as you need to scroll a table, you probably need
more elements to make it be really great.
One thing I'm slightly unsatisfied with, though, is the border
situation. I added a half pixel border to the cell so they all sum up to
1px, but there are cases where there's a tiny space between rows and I
don't quite know where that's coming from and how it happens. But I
think it's a reasonable improvement overall.

Release Notes:
- agent: Improved table rendering in the agent panel, ensuring cell text
wraps, not going off-screen.
