Title
fix(templates): add health checks for Evolution API, Redis, and Postgres in compose config

Changes

• Add health checks for all services:
  • api (Evolution API): internal HTTP GET on http://127.0.0.1:8080/ (2xx = healthy), with start_period: 60s, retries: 30, timeout: 5s.
  • postgres: pg_isready -h 127.0.0.1 -U $${POSTGRES_USER} -d $${POSTGRES_DB}, with sensible retries/start period.
  • redis: redis-cli ping, with sensible retries/start period.
• Orchestrate startup via depends_on with condition: service_healthy so api waits for postgres and redis.
• Fix env interpolation of SERVER_URL to ${SERVICE_URL_EVO} (prevents literal value).

Issues

• N/A

Testing

• Brought stack up with Docker Compose v2.x.
• Verified service health:
  • docker compose ps shows api, postgres, redis as healthy.
  • curl -sS http://127.0.0.1:8080/ returns 200 from Evolution API.
• Confirmed stable startup (no unhealthy/SIGTERM loop).

Backwards compatibility

• Non-breaking; only adds observability and a sane startup order.
