Implements E2E encryption for threshold signing requests, mirroring the existing pattern used for decryption requests. Key changes: - Add makeSigningRequests() helper to encrypt signing requests using ephemeral session keys and ECDH-derived shared secrets - Add decryptSigningResponses() helper to decrypt signing responses - Update SigningCoordinatorAgent.getParticipants() to extract signingRequestStaticKey from contract - Update PorterClient.signUserOp() to use encrypted requests/responses - Remove old plaintext signing types and decodeSignature() function - Update tests with signingRequestStaticKey mocks The encryption is transparent to users - the public API (signUserOp) remains unchanged. Depends on: - nucypher-core PR nucypher#116 (encryption types) - nucypher-contracts PR nucypher#438 (signingRequestStaticKey field) - nucypher PR #3666 (Porter encrypted signing endpoint)

The encryption is transparent to users - the public API (
