event: scope trade helpers to Serde builds

- Gate trade canonicalization collections and JSON helpers behind the Serde feature.
- Keep no-default-features builds free of unused imports and dead-code warnings.
- Preserve the existing default-feature protocol and canonicalization behavior.
- Verify formatting and strict Clippy across default and minimal feature sets.
