Overlay Docker para Coolify: notificación de leads API sobre imagen pública Relaticle

FROM ghcr.io/relaticle/relaticle:latest + COPY de los 5 ficheros
custom (migration + Notification + Action + 2 Observers) que
implementan la notificación in-app/email a un team cuando se crea
una Company o People vía API con creation_source=API.

Se elige overlay en vez de fork completo para no perder las
mejoras de upstream en cada build.
