feat: auto-scroll long chat title once on load + on tap (#612)

* feat: auto-scroll long chat title once on load + on tap

* fix: resolve state delegate + suspension compile errors in AutoScrollingTitleText

* fix: use Int scroll offset for animateScrollTo

* fix: measure real container width for title marquee (was always Infinity)

* fix: ease the title marquee scroll (FastOutSlowInEasing + glided return)

* fix: address agy review — cancel overlapping scrolls + one-shot on-load guard + clickable on box

* fix(ui): smooth out top app bar collapse transition

Use dynamic layout padding based on scroll offset to prevent blank gap at the top of content when app bar collapses.
