Dedupe disabled_quantizers units by importing default_disabled_quantizers

Before: huggingface/{nemotron_vl,phi4mm}/ptq/disabled_quantizers.yaml each
duplicated the 14-entry default_disabled_quantizers list verbatim and then
appended the model-specific exclusions.

After: both units use multi-document YAML to declare an `imports:` section,
`$import: default_disabled_quantizers` as the first list entry, and only
the model-specific exclusions explicitly. Recipes that import these units
are unaffected; the resolved quant_cfg is unchanged.
