v4.5.0

Android & mobile UX release — comprehensive touch device fixes,
soft-keyboard handling, fan curve persistence, and accessibility
improvements across the entire app.

• Fixed: fan curve now loads from the PS5 on screen open — the
  FanCurve screen fetches the persisted threshold via a new
  fan_curve_get engine command on mount, so you see the actual saved
  curve instead of defaults. A persistence info banner communicates
  that the curve survives reboots and rest mode.
• Soft-keyboard avoidance — added interactive-widget=resizes-content
  to the viewport meta, switched all modal/sheet max-heights from vh
  to dvh, and added a visualViewport listener that scrolls the
  focused input into view when the keyboard appears. No more hidden
  text fields behind the on-screen keyboard.
• Numeric keyboard hints — all numeric inputs (ports, temperatures,
  fan duty, speed caps, counts) now have inputMode="numeric" or
  "decimal", and all IP address fields have inputMode="decimal".
  Android shows the numeric keypad instead of the full alphabet.
• Fixed: Toggle no longer distorted on touch devices — the global
  44px touch-target rule was stretching the Toggle switch into a tall
  rectangle. The CSS now excludes role="switch" and properly targets
  role="tab", role="menuitem", role="option", etc. instead of
  blindly catching every <button>.
• Minimum text size enforced — all sub-12px text bumped to text-xs
  (12px). Bottom nav labels, badges, hints, section headings, and
  metadata text are now comfortably legible on mobile.
• Reactive responsive tier — Sheet and Drawer components now use the
  useResponsiveTier() hook instead of a one-shot matchMedia check,
  so they respond correctly to orientation changes and window resizing.
• Accessibility: aria-labels on icon buttons — all icon-only buttons
  in PlaylistsPanel, NotificationInbox, and ConsoleTabs now have proper
  aria-label attributes for screen readers.
