agent: Display full terminal output without scrolling (#31922)

The terminal tool card used a fixed height and scrolling, but this meant
that it was too tall for commands that only outputted a few lines, and
the nested scrolling was undesirable.

This PR makes the card be as too as needed to fit the entire output (no
scrolling), and allows the user to collapse it to fewer lines when
applicable. Making it work the same way as the edit tool card. In fact,
both tools now use a shared UI component.

Release Notes:

- Agent: Display full terminal output
