feat(mflux_image_edit): Qwen-Image-Edit LoRA support

mflux-generate-qwen-edit already exposes --lora-paths/--lora-scales; wire them
to params.loras (['multiple-angles=1.0', ...]). Names resolve by filename stem
or fuzzy match across QWEN_LORA_DIRS (default ~/Documents/localmodels/QwenLora)
so John can drop new .safetensors in and use them by short name. Misses log
loudly instead of failing the job.
