Subject: [PATCH] feat(capacitor-next): add Gateway API HTTPRoute support

Add native HTTPRoute support to the capacitor-next Helm chart.

Changes:
- add templates/httproute.yaml
- add httpRoute configuration block to values.yaml
- support configurable apiVersion and kind
- support parentRefs, hostnames, annotations, and matches
- default to PathPrefix / when no matches are provided

Validated with:
- helm lint
- helm template
- real deployment in cluster using Cilium Gateway API
- successful routing through Gateway + HTTPRoute to capacitor-next
