Mohamed Boudra cc744cc669 feat(app): let users set the chat and Markdown content width (#5680)
* feat(app): let users set the chat and Markdown content width

Wide and ultrawide screens were stuck with an 820px reading column. The
width is now an Appearance setting that flows through the Unistyles theme,
like the font sizes, so every content surface picks it up.

The stored value stays null until the user picks a width, so a future
change to the default reaches everyone who never customized it. Reset
writes null back.

The native composer dock keeps plain React Native styles and takes the width
inline because those styles land on Reanimated views, where theme-driven
Unistyles crash on theme changes.

* fix(app): pass the content width into the web stream viewport

The viewport read app settings itself, which required a QueryClient in every
render of the stream strategy. The agent stream view already reads settings,
so it hands the width over with the rest of the render input.
