fix: canonicalize deploy job names

[vigneshrajsb]

Summary

• add a shared helper for canonical Kubernetes deploy job names
• use the helper in native Helm so manifest generation, monitoring, and log archival all share the same truncated name
• use the helper in the Kubernetes apply path so job creation and monitoring cannot diverge for long deploy UUIDs

Testing

• pnpm exec jest --runInBand src/server/lib/kubernetes/tests/jobNames.test.ts src/server/lib/nativeHelm/tests/helm.test.ts src/server/lib/tests/deploymentManager.test.ts
