 Fix FlashAttention fp32 crash with DoRA (use_dora=True) (#6526) 
* Fix FlashAttention fp32 crash with DoRA (use_dora=True)

DoRA upcasts lora_magnitude_vector to fp32 for the optimizer, which promotes
the q/k/v_proj output to fp32. FlashAttention only accepts fp16/bf16, so the
fp32 q/k/v raised 'FlashAttention only support fp16 and bf16 data type'.
Downcast q/k/v to the compute dtype before the flash kernels.

Fixes #1013

* Apply kwarg-spacing format hook to DoRA dtype test (pre-commit)

* DoRA+FA2: downcast any fp32 among Q/K/V and clamp to a flash-supported dtype

* Tighten code comments (no logic change)
