fix(comfyui): port 8888, emptyDir storage, liveness probe (#18)

- Change container port from 8188 to 8888 (Caddy proxy binding)
- Remove PVC, use emptyDir for ephemeral models/output
- Replace startup + readiness probes with single liveness probe
- Remove explicit COMFYUI_FLAGS (container defaults work)
- Pod now reaches Ready state immediately after image pull

Fixes GPU contention by using ephemeral storage. ComfyUI now runs and is accessible at https://comfy.riotpiao.comReviewed-on: #18
