refactor: CPU config to millicores, fix replica health, reorder tabs

- Rename cpuShares to cpuRequest (millicores), cpuLimit from cores to
  millicores. ResolvedContainerConfig translates to Docker-native units
  via dockerCpuShares() and dockerCpuQuota() helpers. Future K8s
  orchestrator can pass millicores through directly.
- Fix waitForAnyHealthy to wait for ALL replicas instead of returning
  on first healthy one. Prevents false DEGRADED status with 2+ replicas.
- Default app detail to Configuration tab (was Overview)
- Reorder config sub-tabs: Monitoring, Resources, Variables, Traces &
  Taps, Route Recording
