fix: correct ward_rune MORE type, add flat WardRegen base, harden TotalNetRegen test

- ModParser: rename ward_rune_maximum_ward_ to ward_rune_maximum_ward_+%_final
  and change INC to MORE (_final suffix always denotes a MORE multiplier in GGPK)
- CalcDefence: read WardRegen BASE sum so flat per-minute bonuses are no longer
  silently ignored; convert from per-minute to per-second and include in breakdown
- TestWard: replace non-falsifiable TotalNetRegen assertion (== nil or ...) with a
  degen-triggered test that guarantees TotalNetRegen is computed and correct;
  add new test verifying Ward MORE stacks multiplicatively with INC
