feat(v1.5.1): renomeação OpenSheets → OpenMonetis + multi-domínio

Renomeia o projeto em ~40 arquivos (package.json, manifests, layouts,
componentes, server actions, emails, Docker, docs, landing page).
Adiciona suporte a multi-domínio via PUBLIC_DOMAIN onde o domínio
público serve apenas a landing page sem botões de auth.
