Sensitive Data Exposure

Require encrypted transport before sending the ServiceAccount token.
When auth.token_path is configured, the client sends the projected token in the Authorization header. The default http://hyperfleet-api:8000 URL therefore exposes the token to network observers. Reject non-HTTPS API URLs when authentication is configured, and retain certificate validation. Update configs/adapter-config-template.yaml, charts/values.yaml, and charts/README.md so the documented defaults cannot enable this combination.

Same as the sentinel PR, one change before merge, the scheme needs to be a config value rather than a constant.

Same issue as openshift-hyperfleet/hyperfleet-sentinel#264. The API's JWT middleware only takes Bearer, so a hard-coded ServiceAccount breaks JWT_AUTH_ENABLED deployments without the gateway and the operator-managed API, and blocks 1484. Suggest a Scheme field on AuthConfig defaulting to Bearer:
scheme := c.config.Auth.Scheme
if scheme == "" {
scheme = "Bearer"
}
httpReq.Header.Set("Authorization", scheme+" "+tok)Infra sets ServiceAccount only when EXT_AUTHZ_ENABLED=true.

Needs a scheme: Bearer value here, surfaced as HYPERFLEET_API_AUTH_SCHEME alongside the token path and cache TTL env vars so the helmfile can set it.

This sits under Fixed but it's a behaviour change, and a breaking one for in-app JWT users if the scheme stays hard-coded. Move it to Changed, and mark BREAKING unless the default stays Bearer.
… requests Adds clients.hyperfleet_api.auth.scheme (Helm: adapterConfig.hyperfleetApi.auth.scheme), defaulting to Bearer for backwards compatibility. Set to ServiceAccount when fronted by a gateway that differentiates human-jwt callers from machine callers. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
