Soluciona el error "invalid reference format" que ocurría cuando se
generaban tags Docker con formato inválido como ":-bcbb6d2".

Cambios en workflow:
- Elimina prefix={{branch}}- del tag type=sha que causaba el formato
  inválido cuando branch estaba vacío
- Simplifica a type=sha,format=short para generar tags como sha-bcbb6d2

Cambios en Dockerfile:
- Añade declaraciones ARG con valores por defecto para BUILD_DATE,
  VERSION y REVISION (dev, unknown)
- Añade labels OCI estándar para metadatos de imagen
- Garantiza que las variables siempre tengan valores válidos

Esto previene errores como:
ERROR: failed to build: invalid tag "ghcr.io/dawnsystem/intellidocs-ngx:-bcbb6d2"
