Phase 3: the Mangrove Mire poisons anyone without Mire Waders

- Companion mod zone hazards (zone/ZoneHazards.kt, data in
  data/cobblesurvival/zone_hazards/): in the Mire a player without an
  item from #cobblesurvival:mire_protection gets Poison every 5 seconds,
  with a one-time warning. Potions, milk and golden apples still help.
- Mire Waders: KubeJS leather boots, dropped by the Westmarch and Verdant
  Jungle guardians (the zones before the Mire), per Adrian's boss rule.
- Self-test mire_poisons_without_waders.
- Allow-list Cobblemon's misspelt jigsaw state in
  habitats/parched_peat_bog7.nbt, which test players now reach.
