[DEVOPS] Add Docker health checks to all services in docker-compose

[dev-fatima-24]

Priority: medium

Description

The docker-compose services have no health checks, so Docker cannot determine if a service is actually ready to accept connections. Health checks must be added for all services so that dependent services wait for their dependencies to be healthy before starting.

Acceptance Criteria

• PostgreSQL health check uses pg_isready
• Redis health check uses redis-cli ping
• Backend health check calls GET /health
• Frontend health check calls GET /
• All dependent services use depends_on with condition: service_healthy
