chore: pending worktree changes (k8s probe, profile loader, e2e Makefile)

- k8s/deployment.yaml: bump startup-probe failureThreshold from 12 to 24
  (70s -> 130s max startup time) to give the app more headroom on cold start.
- lib/towerops/profiles/yaml_profiles.ex: defer YAML profile loading from
  init/1 to a handle_info(:load_profiles, ...) so the supervisor (and Bandit)
  come up immediately and the profiles populate in the background within ~60s.
- e2e/Makefile: convenience target wrappers around the existing npm scripts.
