fix: whitelist editor keyboard/mouse navigation + highlight gating, My Shows w on focused show

Whitelist editor (Preferences > Auto Download Whitelist):
- input focus driven by nav.inputFocused() (SearchPage pattern) so Esc
  deterministically defocuses and j/k/Space/Enter browse the suggestions
- suggestions react to mouse: click focuses the row and toggles membership
- no accent bg / no marker on any suggestion while the input is focused
- s re-enters typing mode; suggestion rows scroll into view

Search page: recent-searches rows get no bg and no marker while the query
input is focused (previously the focused row fell into the inactive branch
and rendered the border color as a background).

My Shows: w toggles the focused show in/out of the auto-download whitelist
at the show list (depth 0), with a whitelist marker on the row and a hint in
the preview pane (scope: whitelist).
