Feature: Add health endpoints to windmill workers and LSP

[peaklabs-dev]

I am a developer at Coolify and I am integrating your service as a template. The problem is at the moment I am performing "fake" health checks on all workers and on the LSP, it would be great if these actually have a /health endpoint or simmilar we could check. If this already exists please let me know where, if not I would love to see it.
