hold clef-candle at replicas 0 until the image carries the GDN fix

candle-vllm PR #5 (the conv fix) could not be merged, so CI has not published
a :sm70 image containing it. Deploying clef against an older :sm70 fails
silently: the delta rule returns zero on all 24 linear-attention layers and
/v1/systemone still answers 200 with well-formed but wrong classifications.

Raise to 1 once a :sm70 build from the fix merge exists.
