New SPA UI with 4 views:
- Case list (#/) with status cards and document counts
- New case wizard (#/new) with 4-step form: details, parties, schedule, review+create
- Case view (#/case/:id) with grouped documents and drag-drop upload with tagging
- Legacy upload (#/upload) for backwards compatibility
Auto-creation pipeline in wizard step 4:
1. Creates case in legal-ai DB with local git repo
2. Creates Gitea repo in 'cases' org and pushes initial commit
3. Creates Paperclip project via direct DB insert
Document upload with smart rename:
- scan_001.pdf -> כתב-ערר-קובר-1130-25.pdf
- Based on doc_type + party_name + case_number
New files:
- web/gitea_client.py: Gitea REST API client
- web/paperclip_client.py: Paperclip embedded DB client
