feat: integrate MorphTx v2 (excluding prover)

[curryxbo]

Summary

• Pin go-ethereum to 2548caac (MorphTx v2 envelope 0x7f || 0x02 || RLP, including empty authorizationList) and bump all Go modules via Makefile.
• Wire morphTxV2Time into genesis config and set it to 0 on devnet so v2 is active from genesis.
• Keep MorphTx v2 bytes intact in batch decode and derivation (empty and non-empty auth lists), with round-trip tests.

Test plan

• go test ./common/batch ./node/derivation and genesis layer_two test
• make update is a no-op against the pinned geth commit
• make devnet-up then send MorphTx v2 (empty list + one authorization) via eth_sendRawTransaction, confirm eth_getTransactionByHash returns version: "0x2" and authorizationList

Walkthrough

The pull request updates the pinned go-ethereum revision, adds MorphTx V2 batch round-trip coverage, and adds optional MorphTx V2 activation configuration to genesis generation.

Changes

MorphTx V2 integration

Layer / File(s)	Summary
Update go-ethereum dependencies Makefile, go-ethereum, */go.mod	The repository now references go-ethereum revision 2548caac16b2d5a2021a6eba0aa23d7506230439. The node module declares uint256 as a direct dependency.
Preserve MorphTx V2 batch data common/batch/blob.go, common/batch/blob_test.go, node/derivation/batch_info_test.go	The decoder documentation describes V0 and V1+ MorphTx envelopes. Tests cover MorphTx V2 encoding, decoding, re-encoding, hashing, set-code authorizations, and batch parsing.
Configure MorphTx V2 genesis activation ops/l2-genesis/deploy-config/devnet-deploy-config.json, ops/l2-genesis/morph-chain-ops/genesis/*	DeployConfig accepts morphTxV2Time. NewL2Genesis passes the optional timestamp to ChainConfig. Genesis tests verify activation at timestamp zero.
