This commit moves the ReferenceDAProofValidator contract and tests from nitro-contracts to contracts-local, as this is a reference implementation that doesn't need to be part of the core nitro-contracts package. The solidity contract was already reviewed in OffchainLabs/nitro-contracts#357 Since the Reference DA contract is now available, this commit activates contract-based certificate validation by uncommenting the ValidateWithContract calls in certificate.go, reference_reader.go, and reference_validator.go. These were previously disabled with TODO comments waiting for contract merge. This commit also includes some changes required for nitro-testnode to work in CustomDA mode with Reference DA. It Ensures contracts are available in Docker builds by copying both contracts/ and contracts-local/ directories. It also adds ReferenceDA signing key to config dump exclusion list to prevent accidental exposure of private keys. This change was merged into the custom-da branch in: #3803 Other changes required that were needed for the standalone daprovider to work with nitro-testnode were: - New parent-chain-node-url and parent-chain-connection-attempts config - L1 client creation in daprovider startup for ReferenceDA mode This change was merged into the custom-da branch in: #3819
