feat: improve sequencer healthcheck with HealthStatus response
Previously check_health() always returned Ok(()) - completely useless.

Now returns HealthStatus { chain_height, is_healthy } so clients can:
1. Call check_health() once to get current chain_height
2. Wait a few seconds
3. Call again - if chain_height increased, sequencer is healthy
