fix(docker): Update all Dockerfiles to use golang:1.24.7-alpine

Updated 6 Dockerfiles to match go.work requirement (>= 1.24.7):
- deploy/docker/cn-dms/Dockerfile
- deploy/docker/o2-client/Dockerfile
- deploy/docker/orchestrator/Dockerfile
- deploy/docker/ran-dms/Dockerfile
- deploy/docker/tn-agent/Dockerfile
- deploy/docker/tn-manager/Dockerfile

Changed from: golang:1.23-alpine
Changed to: golang:1.24.7-alpine

Fixes Docker build error: go.work requires go >= 1.24.7 (running go 1.23.12)
