feat: Implement PF2e Alchemy and Rest system

Alchemy System:
- Versatile Vials tracking with refill functionality
- Research Field display (Bomber, Chirurgeon, Mutagenist, Toxicologist)
- Formula Book with search and level filtering
- Advanced Alchemy (daily preparation) for infused items
- Quick Alchemy using versatile vials
- Normal Alchemy for permanent crafted items
- Auto-upgrade system for formula variants (Lesser → Greater)
- Effect parsing with damage badges (damage type colors, splash, healing, bonus)
- German translations for all UI elements and item effects
- WebSocket sync for all alchemy state changes

Rest System:
- HP healing based on CON modifier × Level
- Condition management (Fatigued removed, Doomed/Drained reduced)
- Resource reset (spell slots, focus points, daily abilities)
- Alchemy reset (infused items expire, vials refilled)
- Rest modal with preview of changes

Database:
- CharacterAlchemyState model for vials and batch tracking
- CharacterFormula model for formula book
- CharacterPreparedItem model with isInfused flag
- Equipment effect field for variant-specific effects
- Translation germanEffect field for effect translations
- Scraped effect data from Archives of Nethys (205 items)
