Fix Helm chart for Kubernetes deployment (HYPERFLEET-312)

- Fix bind addresses to use :PORT format for all interfaces
- Add health and metrics ports to deployment
- Fix health probe path from /healthz to /healthcheck
- Add app.kubernetes.io/component label to differentiate from PostgreSQL
- Add .helmignore to exclude .git from chart packaging
- Add configurable server bind addresses in values.yaml
