fix(mobile): terminal and layout fixes for touch devices

Mobile-focused fixes for the web UI: keyboard-accessory layout and
overlap, native input visibility above the keyboard, CJK input handling,
terminal touch scrolling, tab-menu tap targets, mic-recording glow
containment, and mobile resize/keyboard-state handling on tab switch,
plus mobile visual-regression test coverage and snapshots.
