Replace use_fp4_indexer_cache with indexer_kv_dtype in the DSV4 Flash/Pro recipes, following InferenceX #3274: mxfp4 on Blackwell, preserving RTX PRO 6000's fp8 override. Update matching guide references.

Validation: recipe JSON API build and 80 generated command configurations passed.

Code Review

This pull request updates the configuration files for DeepSeek-V4 models (Flash, Flash-Vision-Exp, and Pro) by replacing the --attention_config.use_fp4_indexer_cache parameter with --attention_config.indexer_kv_dtype. The parameter values have been updated from booleans to specific data types (mxfp4 or fp8) across various hardware and strategy overrides, as well as in the documentation guides. There are no review comments to address, and I have no further feedback to provide.
