fix: correct all deployment configs from on-chain data, add dev presets

- Fix all mainnet pool IDs (ETH, BSC, Base) — verified via cast call on-chain
- Update all URLs to *.2.o.cash (prod3)
- Populate Base mainnet tokens (ETH + USDC, was empty)
- Add dev presets: ETH_DEV, BSC_DEV, BASE_DEV, SEPOLIA_DEV, BSC_TESTNET_DEV
- Remove unused MAINNET_CHAINS/TESTNET_CHAINS arrays
- Improve seed validation error message
- Update README Quick Start to use SEPOLIA_TESTNET preset
