Add hide chat option to the TUI

[ItsJooL]

I sometimes (particularly when using in K9s) would rather have the full view for the log details. It's personal preference and taste, but for me with long messages even when I have wrap enabled I find it easier to digest with the 30% extra space.

The change is opt-in so no issues for existing users.

Ahh makes sense - will take a look!

🟡 Changes recommended

The log detail modal height calculation doesn’t adjust when the tabs row is omitted (chat hidden), reducing available vertical space and likely leaving unused space in the modal.
