Optimize mobile chat and keyboard mechanics for a robust and great UX on any page.
This PR addresses common mobile chat issues by improving keyboard detection across iOS and Android, ensuring the composer stays above the keyboard, enhancing scrolling behavior to auto-scroll to the bottom, and refining viewport handling with
100dvhand body scroll prevention. It also includes touch interaction improvements like minimum font sizes and tap targets, and performance optimizations for smoother scrolling.
