Development - Docker ARM 4.x - Adapt multi-architecture Docker build

[c-bordon]

Related #2097

Description

Make the necessary changes for multi-architecture construction that have been detected in the indicated spike.

Functional requirements

• Multi-platform Docker images

  • Each current Intel-only image must be migrated to a multi-architecture image (AMD64 + ARM64) using Docker buildx manifests.
  • No separate -arm tags will be published.

Implementation restriction

Multi-platform images must behave identically to the current Intel-only images (same base image, entrypoints, environment variables, config behavior).
