Spanish Tax Compliance Notice (Veri*Factu / RRSIF)

The optional `verifactu` module integrates with the Spanish tax authority
(AEAT) under Real Decreto 1007/2023. Under that regulation, every
deployment of a Sistema Informático de Facturación (SIF) has a
"productor del SIF" who is legally responsible for the software's
compliance and who must sign a declaración responsable. That role does
not transfer with the source code: the producer is whoever deploys and
operates this software in production for issuing real invoices in
Spain. The DentalPin Contributors do not act as producer for any
deployment they do not themselves operate. Operators (SaaS providers,
integrators, or self-hosting clinics under autodesarrollo) are solely
responsible for completing the producer wizard, signing the declaración
responsable, validating end-to-end against AEAT preproduction, and
keeping the software up to date with regulatory changes. See
`backend/app/modules/verifactu/README.md` for details.
