Give Perkeo its consumable wants; make theme fragility a decision

Perkeo duplicates a RANDOM held consumable (card.lua:2788), so Spectral
and Planet supply feed it exactly like Tarot supply always did - and the
spectral_gen theme gains the third member it needed (the Seance +
Perkeo negative-spectral archetype, now discoverable three ways).

The other five two-member themes (diamonds, hearts, four_kind, gold_gen,
stone_gen) are vanilla reality: no third joker exists. They get
FRAGILE_OK verdicts in audit.lua, rendered in AUDIT.md, and the audit
now fails on a fragile theme with no verdict - or a stale verdict for a
theme that grew - the same discipline as the silent-joker list.
