Pull request overview

Updates the Canton/go-daml dependency set and adds a regression test to ensure CCIP DeployRateLimiter enum fields are encoded using the expected ordinal-byte wire format.

Changes:

• Bump github.com/smartcontractkit/chainlink-canton and github.com/smartcontractkit/go-daml (plus associated indirect dependency updates).
• Add TestDecoder_DeployRateLimiter_EnumFields to validate enum encoding/decoding and round-trip behavior for DeployRateLimiter.
• Refresh go.sum to match the module graph after the dependency bump.
