refactor: migrate all DevEtl files to protobuf source

Replace JsonZstdFileSource with ProtobufZstdFileSource across all 20
DevEtl pipeline files. This removes the need for manually defined
JsonColumnSchema arrays as protobuf files embed their schema.

Changes per file:
- Remove using JdeScoping.DataSync.Dev.Models
- Remove private JsonColumnSchema[] Schema array
- Change CacheFileName from .json.zstd to .pb.zstd
- Change WithSource from JsonZstdFileSource to ProtobufZstdFileSource
