fix: count weapon cost when target evades/dodges your attack

- Check evade type for 'target Evaded' or 'target Dodged'
- Count weapon cost on those events (you fired but missed)
- Armor decay still only counted on actual damage taken
- Fixes: weapon cost now accurate for all shots including misses
