Daniel Han db72016c39 Fix silent LoRA drop and wasted transformer prefetch on GGUF quant loads
Two live-test findings on the images load path:

- transformer_quant with baked LoRAs, when the dense quantized build is
  declined for memory or fails: the load completed as a plain GGUF with the
  adapters silently dropped (HTTP success, supports_lora=false after the
  fact) -- wrong output with no signal. The load now fails with the recovery
  options (drop the adapters, free VRAM, or pick a smaller model). Weight-0
  adapters still count as no bake request, and the plain no-LoRA decline
  keeps its silent GGUF fallback.
- A fresh GGUF load on a small GPU prefetched the base repo's full bf16
  transformer shards (~47 GB on Qwen-Image) because the dense-quant prefetch
  widening only checked scheme viability, not whether the device could ever
  hold the candidate resident. Gate the widening on total device capacity
  (reserve + 0.85 margin, the plan_fits_total_capacity bar) so a card that is
  certain to decline the dense build never pays the download; capable devices
  keep the prefetch.
