Fix four tag gaps and a contradiction found by the full-database audit

Cross-checked all 150 jokers' tags against JOKER_EFFECTS.md and the dump:

- Drop the Vampire + Marble clash: Vampire gains xMult from any non-base
  scoring card (card.lua:3907), Stones included, so Marble feeds it --
  the same shape as the Midas Mask pair. The data even scored the duo
  as a combo while warning against it. Stone-build harm stays covered
  by the Vampire + Stone Joker line.
- Delayed Gratification wants discards_up: it pays per unused discard,
  same shape as Banner.
- The Idol wants suit_flex: it checks is_suit (card.lua:3530), so
  Smeared doubles its eligible cards, like Ancient Joker.
- 8 Ball wants retrig_scoring: the 1-in-4 rolls per scored 8 in the
  individual pass (card.lua:3507), so retriggers re-roll it.
- Reword the suit give phrasings: nothing vanilla turns cards into a
  suit, so 'turns cards into Spades' was a lie whenever Blackboard sat
  across from a one-sided giver like Wrathful or Arrowhead.
