chore: update CI actions, Go 1.25, Alpine 3.22

Updates CI to latest major actions (checkout v5, setup-go v6, upload-artifact v5, CodeQL v4) for security and compatibility.
Uses stable major tag for autofix action.
Updates Docker images to Go 1.25 and Alpine 3.22 to leverage newer toolchain and patched bases.
