ops(litellm): repoint gen/qwen-large/summarizer-large aliases -> qwen3.6-40b-deckard (Deckard trial)

Displaced qwopus-122B on ana-ml2 GPU0:8013 with robbatt/Qwen3.6-40B-Deckard-NVFP4
(stock vLLM 0.23.0, loaded clean: hybrid attn + multimodal + fp4_gemm all green).
Repointed the 5 role aliases (gen, gen-reasoning, qwen-large, qwen-large-reasoning,
summarizer-large); added the qwen3.6-40b-deckard true-name record; left the true
names qwen3.5-122-a10b[-reasoning] to 404 (no-false-alias). Operator-directed
trial-by-fleet-traffic; revert path in the config banner + live backup
config.yaml.bak-pre-deckard-20260701-001036.
