Support for LoRA / adapters in AceStepPipeline #14060

Description

@Nib-git

Hello,
First of all, thank you for adding the ACE-Step 1.5 pipeline. It's working nicely!
I noticed that LoRA support doesn't seem to be implemented yet in AceStepPipeline.
When trying to load a LoRA I get this error:
'AceStepPipeline' object has no attribute 'set_adapters'
(using the standard Diffusers method: load_lora_weights + set_adapters)
Additionally, this was also reported in the Amuse project (which uses Diffusers under the hood):
saddam213/AmuseAI#54

I'm using the XL SFT and Turbo variants on an AMD RX 7900 XTX, both in Amuse and directly with Diffusers.
Would it be possible to add LoRA support for this pipeline in the future? It would be very useful for style transfer and personalization.
Happy to provide more details, logs, or help test if needed.
Thank you!
