Add tip audit logging, CFR alignment tests, and multiway scenarios

Three confidence features for the poker tip system:
- Tip audit table (holdem_tip_audit) logs every tip with full context
  for bulk review after real sessions
- CFR alignment test validates all 32 scenarios against the trained
  5M-iteration policy — rules engine never contradicts the bot's AI
- 8 new multiway test scenarios covering all streets and key decisions
