feat(deployment): live elapsed time counter for ongoing deployments

[acarranoqovery]

Summary

• Service and environment overview "Last deployment" sections now show a live XX seconds ago counter (ticking every second) when a deployment is ongoing, instead of relying on backend polling
• Deployment logs header (XXm : XXs stopwatch) uses a local ticker seeded from last_deployment_date when the deployment is ongoing

Testing

• Changes tested locally in the relevant Console's pages and Storybooks
• yarn test or yarn test -u (if you need to regenerate snapshots)
• yarn format
• yarn lint

PR Checklist

• I followed naming, styling, and TypeScript rules (see .cursor/rules)
• I performed a self-review (diff inspected, dead code removed)
• I titled the PR using Conventional Commits with a scope when possible (e.g. feat(service): add new Terraform service) - required for semantic-release
• I only kept necessary comments, written in English (watch for useless AI comments)
• I involved a designer to validate UI changes if I am not a designer
• I covered new business logic with tests (unit)
• I confirmed CI is green (Codecov red can be accepted)
• I reviewed and executed locally any AI-assisted code
