- Update pool-info to show correct price calculations
- Fix position-info to use computePoolAddress from SDK
- Improve quote-position to handle decimal-adjusted ticks correctly
- Fix open-position and add-liquidity multicall implementations
- Add comprehensive debug logging for troubleshooting

The main issue was that Uniswap V3 ticks represent prices in raw token units,
not human-readable prices. For WETH/USDC pairs, this results in negative ticks
due to the 12 decimal difference between the tokens.
