feat: add AI deadline extraction frontend page (Phase 2M)

- ExtractionForm: PDF dropzone (react-dropzone) + text textarea + case selector
- ExtractionResults: review table with edit/remove per row, confidence color-coding
- Page at /ai/extract: upload -> analyze -> review -> adopt deadlines to case
- Extended API client with postFormData for multipart uploads
- Added ExtractedDeadline and ExtractionResponse types
