More obvious edit mode for query panel

[davepar]

I absolutely love this utility. It's lazygit for databases!

It would be nice if the UI were more obvious about whether the query panel is in edit mode or not. I'm constantly forgetting to hit "i" to edit and escape to get out.

Maybe color can be changed for the cursor and the border?

We have the information at the bottom left, like we have in Neovim with status bar for example, but we also get the cursor changing from ▊ to | in neovim, I don't know if it's possible here, but this is maybe another good option.
