DoT effect: Poison status damage over time

Tests Effect with periodic tickAction. Poison ticks every N seconds dealing damage based on max HP. Verify (a) the library returns per-tick damage when given the tick number, (b) the snapshot policy works (default dynamic: poison damage changes if MaxHP changes mid-poison), (c) total damage over duration matches expected.

Expected output
From the scenario fixture. Numerical values marked as null are placeholders pending rAthena verification.
tickDamage: pending

First poison tick at tick=2. Verify formula evaluates against defender's current state (not snapshotted). Also test: a separate call with the same poison but with a Blessing buff active that raised VIT should yield a different MaxHP and therefore different tick damage — proves dynamic re-evaluation works.

Computed: EffectTickResult

Server-evaluated by calculateEffectTick() from @ro/core.

Stack-aware formulas (e.g. stacks * floor(maxHP * 0.005)) handle scaling themselves; the library does not auto-multiply.
