chore(compose): replace the MinIO image by pgsty/silo in the compose stacks (#606)

The minio/minio image can no longer be pulled from Docker Hub: the upstream
repository was archived on 24 April 2026 and Docker Hub has since removed the
minio/minio and minio/mc repositories (every tag answers 404), which breaks
every fresh deployment of this stack. Silo is the community-maintained fork of
the MinIO server, compatible with the S3 API, the MINIO_* variables, the
server command, the health route, the bundled mc client and the on-disk
format, so the services keep their names, ports, credentials, command and
healthcheck. The latest tag is used to stay aligned with the rest of the
Filigran ecosystem.
