feat: complete ward mechanic wiring (TotalNetRegen, absorption, EHP, ArmourBreak)

- Add ward_regeneration_rate_+% and ward_rune_maximum_ward_+%_final
  stat-ID mappings to SkillStatMap
- Route WardRegen into TotalNetRegen and ComprehensiveTotalNetRegen
  with breakdown display
- Apply RuneWardDamageTaken multiplier in ward absorption formula
  so runic ward drains faster per point absorbed
- Add WardRecoverOnBlock to EHP GainWhenHit loop including both
  restore blocks and accelerated damage forwarding
- Route WardAttackHitPercent into ArmourBreakPerHit in CalcOffence
- Add test for WardRegen computation
