The pipeline create body carries `config.tables[].destinations`, which
the CDC path in pi-factory needs to honor a user-supplied raw Snowflake
table name. The gRPC PipelineV2CreateRequest previously had no `config`
field, so `...body` dropped it on the wire.
Bump protospack to cdc.3 (adds optional `config` string). Serialize
`body.config` into the create request the same way `properties` is
handled, and add `config?` to the ICreatePipelineV2Req DTO so it's
typed. Add a spec asserting the gRPC request carries a stringified
config with the destination intact.
