Deploys and contract calls on the Lux C-Chain signed from a plaintext
mnemonic or a k8s-held private key. Route them through the MPC instead:
pkg/evm derives the account from the keygen secp256k1 pubkey, sends the
transaction digest to the existing CGGMP21 /v1/mpc/sign oracle, and
assembles r,s,v — the key is never reconstructed in one place. SignTx
recovers the sender from the signature it just applied and refuses if it
is not the signer's own account, so a wrong recovery id is caught before
broadcast rather than after. `mpc evm address|recover|sign|tx` drives it
from the CLI. The /v1/mpc/sign HTTP responses now also return v, matching
the KMS and ZAP paths.
