switch library to ratatui

[blacknon]

The library (tui-rs) we were using is no longer under development, so we switch to ratatui, which we forked.

For some reason, as soon as I switched to ratatui, watch/history disappeared...

The following areas are likely to be the cause of the problem.

hwatch/src/app.rs

Lines 288 to 305 in b6e4be7

	// get Area's chunks
	let top_chunks = Layout::default()
	.constraints([Constraint::Length(header_height), Constraint::Max(0)].as_ref())
	.split(total_area);
	let main_chunks = Layout::default()
	.constraints(
	[
	Constraint::Max(total_area.width - history_width),
	Constraint::Length(history_width),
	]
	.as_ref(),
	)
	.direction(Direction::Horizontal)
	.split(top_chunks[1]);
	self.header_area.set_area(top_chunks[0]);
	self.watch_area.set_area(main_chunks[0]);
	self.history_area.set_area(main_chunks[1]);

---

The cause of the bug was found.
Constraint::Max(0) does not calculate the maximum value in ratatui and it is 0.
Therefore, it is corrected to calculate it properly.

Hey, maintainer of ratatui here. Can you point out to me the code/change that broke Constraint::Max for you? I would like to understand what happened there and possibly add a note to the changelog.

Sorry, it was a long time ago and my memory has faded.
I will look into it and if I find out, I will describe it. 🙇
