Fix: gradio 4.44 + pin huggingface_hub==0.23.0 to avoid HfFolder error

Fix: disable SSR mode for HF Spaces compatibility

Fix: move theme to gr.Blocks(), remove from launch() (gradio 5.x)

Switch to fine-tuned Builder117/distilbert-prompt-injection

Pause: placeholder while fine-tuned model trains

Fix Gradio 6.0: move theme param from Blocks() to launch()
