fix(plex): Restart only where an episode has a resume point; the Surprise draw is re-read, not redrawn

Show cards carry resumable (ShowState, from the same rollup) so a part-watched show whose next episode is untouched offers Play, not a Continue and a Restart that do the same thing; plexStarted is the one rule for cards and menus. The Surprise rail's key sits under the discover root: whatever refreshes the rails re-reads the draw (keep=) with its watch state now, kept past the 5-minute gc, and only the reshuffle deals. Closing the player refreshes the Discover rails. A show card's play acts on the last click only, and only where it was made.

+// A show's card in the Browse grid plays (the owner, 2026-10-09): its picture asks the server which
+// episode and opens the player on it; a started show's Restart opens it from the start; its title
+// opens the show's page. The hook is tested on its own (usePlayShow); this is the grid wiring it.
