- DeadlineCalculator: use optgroup to group by UPC/DE
- DeadlineWizard: add section headers for each jurisdiction
- CaseForm: replace hardcoded TYPE_OPTIONS with API-fetched
proceeding types grouped by jurisdiction
- Added 3 new DE proceeding types to DB: DE_PATENT,
DE_NULLITY, DE_OPPOSITION
Frontend api.ts baseUrl is already "/api", so paths like
"/api/cases" produced "/api/api/cases". Stripped the redundant
prefix from all component calls. Rewrite destination correctly
adds /api/ back for the Go backend.
