fix(comfyui): disable k8s service links to fix COMFYUI_PORT env collision

Root cause: k8s Service named 'comfyui' auto-injects COMFYUI_PORT=tcp://...
into pod env, clobbering ai-dock's own COMFYUI_PORT variable which expects
a port number. This broke caddy's proxy config, leaving port 8188 dead.

Fix: enableServiceLinks: false, revert to port 8188 (ai-dock default).
Also bump startup probe failureThreshold 60->120 (20min budget for model loading).
