[Edge] A deploy YAML must mean the same thing whichever flag loaded it

`vllm_omni/deploy/edge/qwen3_tts.yaml` carries `orchestrator:
parallel_stage_init: true`, but `_apply_profile_orchestrator_defaults` ran
only on the `deploy_profile` path. Pointing `--deploy-config` at the same file
loaded its stages and silently dropped the block, so the edge deployment
started sequentially:

    --deploy-profile edge                       30.76 s
    --deploy-config .../edge/qwen3_tts.yaml     63.76 s   (same file)

with nothing in the log to say why. The block now applies however the config
was reached. Explicit arguments still win, and the allow-list stays narrow --
a test checks an unrecognised key cannot be injected through it.
