Credibility pass: the illusion tests roll both ways, and the seams from the last batch are sanded

Scope: 66b5c06..HEAD.

- The rev-27 illusion tests search seeds for a believed and a doubted
  roll and assert fixed life totals; seed 42 alone never believed, so
  the BLUNT pricing went unchecked.
- Three docblocks stranded above newly inserted functions are back on
  their own (openCreatureStack, resolvedBlow, castTrace).
- POWER ATTACK's life trade is one helper instead of three copies; the
  goat's charge distance is one helper for its validator, its ram and
  its pricing.
- The family list loads once into a shared store; the lobby and gallery
  share one talk filter; Board uses the engine's neighbor().
- A creature's blow shows the card that summoned it by the creature's
  kind, not by matching the blow's display name.
