fix(consul): Fix health checks for gRPC services in Docker

Browse Source 
- Add gRPC health check support to Consul registry
  - Services are gRPC-only, not HTTP
  - Consul was trying HTTP health checks which failed
  - Now uses gRPC health checks via grpc.health.v1.Health service

- Update HealthCheckConfig to support both HTTP and gRPC
  - Add GRPC field for gRPC service name
  - Add UseGRPC flag to choose health check type
  - Default to gRPC for services (use_grpc: true in config)

- Fix service address registration in Docker
  - Services now register with Docker service name (e.g., auth-service)
  - Allows Consul to reach services via Docker network DNS
  - Falls back to localhost for local development

- Update default.yaml to enable gRPC health checks
  - Set use_grpc: true
  - Set grpc: grpc.health.v1.Health

This fixes services being deregistered from Consul due to failed
HTTP health checks. Services will now pass gRPC health checks.
