fix(comfyui): seed custom_nodes/input/output/user dirs under --base-directory

main.py crashed on boot (FileNotFoundError on /storage/custom_nodes) -
--base-directory fully relocates custom_nodes/input/output/user/temp
under it, it doesn't create them or fall back to the image's own
ComfyUI/custom_nodes (which has ComfyUI-Manager baked in). Seed
/storage/custom_nodes from the image's copy on first boot only (skips
once populated), so Manager survives the base-directory switch and
persists across recreates.
