Module projection 

Shared trade read response projection helpers.

The cache/backend layer stores values close to the wire shape. Public Trd_* responses should expose FTAPI semantics consistently across REST, gRPC, raw WS, MCP, and CLI, so market/currency/ratio projection lives here instead of inside one surface handler.
