Use ratatui::run() for managing terminal lifecycle

[nebkor]

This removes the custom tui module for setting up the terminal and panic handlers, and instead uses the new run() function from Ratatui 0.30. Something to note is that I had to change the main func to be non-async, since the run function takes a sync closure, so I used the Tokio runtime's block_on() method inside it; I'd love to see a better way to do that.

It seems the formatting defaults for edition 2024 are slightly different than 2021, which is why all those extraneous changes are in there; they were done automatically.

Perhaps would you mind doing a quick PR for flipping to 2024 edition and then rebasing this change on that.

I'll have to take a deeper look at this to understand the impact on the async changes.

Done! See #143 .

Added a few small tweaks to the approach:

• slapped #[tokio::main] on the app::run method instead of manually building the async runtime
• moved Events::new() into the run method (as it needs the async reactor to run
• renamed draw() to render() and made it accept Frame instead of DefaultTerminal
• put the init call that passes the cli query in App::new()

Does this look good to you?

I love it!
