Create client
Add a client to the catalog with RFC, name, CFDI use, tax zip code and fiscal regime.
MCP tool facturama_write → create_client
write
Saves a client and returns its client_id. It reaches no one and issues nothing, and a wrong entry is fixed in Facturama, so it does not ask for confirmation.
