feat(gowlers-tracking-ledger): improve damage source extraction with proper metadata resolution

- Implement resolveActorFromMetadata() to extract attacker from message metadata UUID
- Implement resolveItemFromMetadata() to extract weapon/ability from attacker's inventory
- Change label format from "Damage (Actor, Weapon)" to "Actor -> Weapon" (e.g., "Goblin -> Scimitar Slash")
- Add support for identifiedInfo, metadata, flavor text, and speaker.alias in priority order
- Add support for Critical and Nonlethal damage modifiers
- Update version to 0.1.19

This properly resolves WHO did the damage (attacker name) and WHAT was used (weapon/ability name),
addressing the missing damage details. Format matches reference macros (macro_activate-hp-tracking.js).
