fix(npc): Cipfried and Dallheim don't cure burning

Both offer free healing and both handle CONDITION_POISON only, so a player
who says "hi"/"heal" while on fire is told they look fine and keeps burning.
They are the two free healers newcomers reach first, so it is the most
noticeable case.

Other healer NPCs already do this: Quentin, Alia, Amanda, Azalea and Cedrik
all handle CONDITION_FIRE alongside poison. This just brings these two in
line with them, adding the fire branch before the poison one so the more
specific condition is matched first.

Counted across data-otservbr-global/npc: 35 NPCs expose a "heal" keyword,
but only some of them handle fire.
