fix(influxdb3-ent): add gRPC/Flight Ingress route

[alespour]

This PR

• adds gRPC/Flight Ingress routing to InfluxDB3 Enterprise chart. It is necessary for querying with v3 client libraries. Keeps a single default ingress host for path-based write/query/Flight routing; an optional ingress.flight.host override is available for ingress-controller environments that require host-level separation of gRPC and HTTP traffic.
• bumps app version to the latest version (3.9.1)

Pull request overview

Adds a dedicated Ingress resource for Apache Arrow Flight/gRPC query traffic to InfluxDB 3 Enterprise queriers, enabling v3 client libraries to query successfully via Flight endpoints.

Changes:

• Add ingress.flight configuration (host/TLS override, gRPC paths, and annotations) to values.yaml.
• Introduce a new Helm template to create a *-flight Ingress routing Flight/gRPC paths to the querier service.
• Bump the chart version to 0.2.0.
