feat: Add new stablepy tasks & tabs (by R-Kentaren)

NEW TASKS (constants.py):
- outpaint: Expand images beyond borders (repaint ControlNet)
- zoe_depth ControlNet: Better depth estimation
- lineart_standard ControlNet: Standard LineArt
- anyline ControlNet: Line detection
- teed ControlNet: Edge detection

NEW TABS (app.py):
🎨 Quick Tasks Tab:
- 10 one-click task shortcuts
- Auto-configures settings for each task type
- Covers txt2img, img2img, inpaint, outpaint, sketch, pose,
lineart, depth, colorize, style transfer

🖼️ Outpainting Tab:
- Direction selection (left/right/top/bottom/all)
- Pixel expansion control
- Dedicated prompt fields for expanded area
- Advanced settings (strength, steps, CFG, seed)
- Powered by stablepy repaint ControlNet
