Closing an episode context menu (or its Rate / File Info sheets) on a
show opened from a Home section scrolled the detail page back to the
top, and on shows with many seasons jumped the season selector back to
the entered-from season. The Home path parks invisible focus on the
initial episode/season target; dismissing the menu restored focus to
that parked node, whose focus-gain auto-scroll then yanked the viewport.
Focus chrome is already keyboard-mode-only, so make the focus-gain
reveal match: FocusableWrapper, FocusableChipStateMixin, and
FocusableTileStateMixin now scroll into view only during keyboard/D-pad
sessions. The gate reads the tracker's live state (new
InputModeTracker.currentMode) because the inherited provider is one
frame stale on the first navigation key of a session. The touch OSK
search submit keeps its jump-to-results via an explicit reveal, matching
the existing pointer-mode convention of pairing requestFocus with an
explicit scroll.
