Studio: account for DeepSeek-V4 compute buffer in context auto-fit (#6940)
* Studio: account for DeepSeek-V4 compute buffer in context auto-fit

DeepSeek-V4-Flash's lightning indexer plus compressed sparse attention reserve a
large context-scaling compute buffer that _compute_buffer_ctx_bytes did not model
(the KQ-mask and dequant-scratch rates both miss it, even with an f16 cache).
Measured on UD-Q4_K_XL at ub 512 it is about 65.5 GiB at 1M context, which the
mask estimate puts near 1.5 GiB, so the auto-fit kept the full 1M train context
and llama-server OOM'd allocating the ~70 GB buffer, then spilled to CPU (~4
tok/s). Add a deepseek4-gated flat plus per-token term so the fit caps the context
(about 256k on a B200) and the model stays fully on GPU.
