fix(dashboard): attach Keycloak token on agent API calls (#90)

+//! Authenticated HTTP client for talking to the compliance-agent.
+//!
+//! Every dashboard server function that hits `comp-dev.meghsakha.com/api/v1/*`
+//! must go through here so the Keycloak access token from the user's
+//! session is attached as `Authorization: Bearer <token>`. Without it
+//! the agent's M7.1 `require_jwt_auth` middleware rejects with 401
+//! "Missing authorization header".
+//!
+//! When Keycloak is not configured (dev convenience), the helper
+//! returns an unauthenticated builder — matching the agent's
+//! pass-through behavior in the same state.
