Replace individual field editors (KVNR, ICD) with a unified edit-mode
approach using data-driven field configuration. A single "Bearbeiten"
button toggles all fields into edit mode with dirty-tracking and
split-save (KVNR via dedicated endpoint for all users, remaining fields
via admin-only general update endpoint).
- Extend Case TypeScript interface with 17 missing backend fields
- Add declarative field config (7 sections, 30 fields) in fieldConfig.ts
- Add useInlineEdit hook with dirty-tracking and split-save logic
- Add EditableField dual-mode component (text/date/boolean/select/textarea)
- Refactor CaseDetail to render sections from config
- ICD section retains its own endpoint with separate save button
