Fix enabler phrasing, wake two silent jokers, read the board order

* The tooltip mis-taught every pure enabler. JCA.explain used a cluster
  tag's `both` text whenever EITHER side was a full member, so Four
  Fingers next to Runner claimed "both reward Straights" -- Four Fingers
  does not reward Straights, it makes them reachable. `both` now requires
  both sides, and every cluster tag carries give/want phrasings.

* Blue Joker and Abstract Joker scored 0 against all 150 jokers. Blue
  Joker scales on #G.deck.cards, so it wants card_gen (DNA, Marble,
  Certificate); Abstract scales on #G.jokers.cards, so it wants joker_gen
  (Riff-Raff is +6 Mult on its own). Both verified in card.lua. Steel and
  Glass Joker look like the same fix but are NOT: they need Steel/Glass
  specifically, and the only enhance_gen givers make Gold and Stone, so
  tagging them would invent a synergy that does not exist.

* Copy jokers are positional and the board order was there all along.
  JCA.copy_source reports what an owned Blueprint/Brainstorm is actually
  copying, including when the target is one of the 29 centers vanilla
  refuses to copy (blueprint_compat = false), or when it is copying
  nothing at all.

* The sell advisor now counts clashes when ranking what to cut. JCA.score
  stays pure -- a trap must never make a card look like a combo -- but a
  joker eating another one's payoff is exactly the one to sell.

The suite caught a real bug while writing this: `(mode == 'right') and
cards[idx+1] or cards[1]` falls through to the LEFTMOST joker when the
right-hand slot is nil, so a rightmost Blueprint would have named the
wrong card. 673 pass here, 9 in-game via the smoke harness.
