fix(tv): only defer subtitle selection when it navigates

The close-first + runAfterInteractions pattern is needed only in the player,
where selecting a subtitle can navigate (replacePlayer for a burn-in switch
while transcoding). On the item detail page the selection just updates state, so
deferring it until after the modal is dismissed re-renders the page after focus
returns and yanks TV focus — leaving navigation stuck. Gate the deferral behind
deferApplyUntilDismissed (set by the in-player caller only); the detail page runs
the selection before closing, preserving focus.
