feat: implement variable token offers and auto-round advancement

- Add variable offer system where P1 can offer any amount of tokens
- Players start with 10 tokens each (P1: pavos, P2: elotes)
- Implement offer/request mechanism with token validation
- Auto-advance rounds after P2 actions or P1 no-offer
- G2: Force offer by default, disable no-offer button when forced
- G3: Wait for shame decision after snatch before advancing
- G4: Implement inverse sanction (P1 gets requested without giving offered)
- Reset rounds to 1 when changing game variants
- Fix OfferControls responsiveness issues
- Hide offer controls after active offer
- Update all G1-G5 components with proper offer flow
