Make the title collapse into the top bar on scroll

Make the titles collapse into the top bar when you scroll on all pages. Like how android 12 does it.

Currently Compose has some problems with nested scrolling and swipe refresh, so I removed it for now, I'll add it back when I've done my research.

This'll be somewhat uneven, caz the collapsed headings gonna be too big when titles are lengthy...
