Loading a trained LoRA at inference (e.g. a fighter LoRA on an image pipeline)
crashed with "cannot import name AwqGEMMQuantLinear" because peft dispatches AWQ
for any non-bnb target when gptqmodel is installed, and gptqmodel 7.1.0 renamed
that class to AwqGEMMLinear. The alias shim existed only in the training path.

Extract it to codai/models/peft_compat.ensure_peft_awq_compat() (cached) and call
it before load_lora_weights in codai/api/images._apply_loras and the acceleration
fuse path; the trainer now delegates to the shared shim.
