Fix workflow execution failures caused by:
- Port conflict: both containers tried to use :8081
- Incorrect split: /app/worker doesn't have 'server' subcommand
- Multiple health check servers competing for same port
Changes:
- Single container: workflows-worker (activity executor only)
- Removed server/worker split
- No HTTP server (Temporal handles gRPC internally)
- Clean env var setup: TEMPORAL_HOSTPORT, MEMORY_SERVICE_URL, etc.
This allows workflows to execute without port conflicts or crashes.
