fix: raise HPP mainnet deploy gasLimit to 60M

HPP is an OP-stack rollup where total gasUsed = L2 execution + L1 data
fee. The L1 data fee is volatile and driven by Ethereum mainnet
conditions. The previous 16M limit was insufficient when L1 fees spiked,
causing OOG failures that consumed the deployer nonce without deploying
the contract.

Setting 60M provides headroom above the worst observed gas usage
(~11.35M on Apr 21 2026) while staying well within HPP's block gas
limit (~1.1 quadrillion).
