QA fixes for KQIII dependency graph

Fixed missing connections:
- O_RECEIVE_PORRIDGE --> A_MIX_COOKIE (porridge is part of poison)
- O_ITEMS_HIDDEN --> A_WAIT_MANANNAN (hidden items before waiting)
- A_APPROACH_DRAGON --> A_CHURN_BREW (approach dragon before attack)

Remaining 12 dead ends are acceptable - they are ingredients
collected and held until spell brewing (implicit inventory use).
