Add multi-mask extraction with count selector and navigation

- Add count selector (1-10) for generating multiple mask variations
- Each mask gets a unique random seed
- Add left/right arrow navigation in mask preview modal when multiple masks exist
- Batch storage system for tracking multiple concurrent extractions
- Webhook handler now uses batch_id:mask_index for routing responses
