Show download state and progress on reader chapter list.

[NGB-Was-Taken]

Issues with my implementation:

• The download state and progress don't update until chapter is scrolled out of the screen and back or the chapter list dialogue is closed and re-opened.
• The button itself still does nothing.

Closes #1207
(I am unsure whether #497 is mentioning this or something else and why Syer mentioned that it's intentional.)

Is this good to merge? I saw a lot of talk about it in the discord

Definitely not. It just "sort of" works. As I mentioned:

The download state and progress don't update until chapter is scrolled out of the screen and back or the chapter list dialogue is closed and re-opened.

I have managed to make it update when the state changes (not committed) . No luck on the progress though. I think I'll be quite busy this week and won't be able to work on this. Should I mark this as draft or something?

Marking it as draft then 👍

Should I add issue 497 to be closed by this? Context is lost without the images and I have no clue if it's mentioning this or something else.

It still doesn't update the state after chapters are automatically deleted.
