Remove JsonMessageCodec from top-level exports

- Removed JsonMessageCodec from compas_eve.__init__ exports
- Moved import back to lazy import in Transport.__init__ to avoid top-level dependency
- JsonMessageCodec should be imported as `from compas_eve.codecs import JsonMessageCodec`
- This keeps the API cleaner and more organized
