Replace harmony-one/bls fork with official herumi/bls-eth-go-binary

[Copilot]

Mirrors harmony-one/harmony#5086 — drops the Harmony BLS fork in favor of the official Herumi package, and updates the harmony dependency to pick up those changes.

Dependency updates

• github.com/harmony-one/harmony → v1.10.3-0.20260728072432-2e5db93591ed (dev, post-#5086)
• github.com/harmony-one/bls removed; github.com/herumi/bls-eth-go-binary v1.37.0 added (indirect via harmony)
• replace github.com/ethereum/go-ethereum bumped v1.9.9 → v1.11.2

Code fixes required by updated dependencies

BLS import path (pkg/keys/bls.go, cmd/subcommands/staking.go, cmd/subcommands/utility.go):

// before
bls_core "github.com/harmony-one/bls/ffi/go/bls"
// after
bls_core "github.com/harmony-one/harmony/crypto/bls/core"

IntrinsicGas relocated and gained a parameter (staking.go, ethtransfer.go, transfer.go):

// before
core.IntrinsicGas(data, false, true, true, isCreateValidator)
// after — package is now core/vm; new isEIP3860 bool at end
vm.IntrinsicGas(data, false, true, true, isCreateValidator, false)

EIP-712 types moved (pkg/governance/eip712.go, pkg/governance/types.go):

// before
"github.com/ethereum/go-ethereum/signer/core"
// after
"github.com/ethereum/go-ethereum/signer/core/apitypes"
