Fixes

chatbot: iOS mobile keyboard handling

Mobile chat panel now stays full-screen fixed and only the composer slides up via padding-bottom = visualViewport keyboard inset, mirroring React Native's KeyboardAvoidingView.

• touchmove preventDefault outside the messages area (real iOS body lock — overflow:hidden alone doesn't stop touch panning on iOS Safari)
• focus({ preventScroll: true }) prevents iOS auto-scrolling the visual viewport on input focus
• overscroll-contain on inner scroll regions to stop rubber-band propagation
• Body scroll lock via position: fixed; top: -scrollY restores scroll on close

No public API changes.
