Map typed RPC errors and add --quiet to records get

Non-streaming RPC dispatch was collapsing every handler error to
INTERNAL, hiding NOT_FOUND and SCHEMA_VIOLATION from the CLI envelope
and forcing exit 4. Route through MapError so typed core errors surface
with their real codes (the streaming path already did this).

Also wire --quiet into records get for parity with create/update/upsert/delete.
