Pull request overview

This PR reverts multiple base image upgrades that were merged without passing CI. The reversal brings Go, Node.js, Ruby, Java (Temurin), .NET, Alpine, Debian, MySQL, Redis, and Kafka images back to previously validated versions, aligning them with the go 1.25.7 directive in go.mod.

Changes:

• Downgrades all Go builder images from golang:1.26.0 back to golang:1.25.7 across the entire codebase.
• Reverts non-Go base images (Node.js, Ruby, Java/Temurin, .NET, Alpine, Debian, MySQL, Redis, Kafka) from versions that did not have CI coverage to previously validated versions.
• Replaces pinned sha256 digests to match the reverted image versions throughout all Dockerfiles.
