feat: click scales with generators (types + quantity), not prod/s

clickGain = base × prestige × tree × (1 + types×2 + totalOwned×0.05)

Click power is now its own system:
- Each generator TYPE owned: +2 to click mult (diversity = power)
- Each generator UNIT owned: +0.05 (stacking helps but less)
- 5 types × 10 each = x13.5 click multiplier from infra alone
- Decoupled from prod/s — buying generators boosts BOTH systems

ClickPanel shows infra breakdown (types bonus + units bonus).
