Combat encounters: Add pre-encounter config modal, targeting fixes, and tracker integration

- Add pre-encounter narrative configuration modal with combat/summary style settings
- Change POV fields to text inputs (default: narrator) for custom character names
- Fix targeting system for enemies with spaces in names (e.g., 'Gilded Thrall 1')
- Display character-specific sprites/avatars in targeting modal instead of generic emojis
- Add combat difficulty scaling guidance to prevent trivial god defeats or endless wolf battles
- Integrate tracker updates in combat summary generation (together mode)
- Update auto-save logs description to clarify file storage vs chat history
- Apply extension theming to Close Combat Window button
