feat: move patient info to top header with React Context

Refactored patient display from separate ClientHeader to integrated EPDHeader.

Architecture changes:
- Implemented React Context pattern for patient data sharing
- Created PatientContext with useState + setPatient for dynamic updates
- Created useSetPatient hook for patient injection from nested layouts
- Created EPDLayoutClient wrapper with PatientProvider
- Context flow: EPDLayout → EPDLayoutClient → EPDHeader (consumer)

UI improvements:
- Removed "Mini-ECD" logo from header
- Left-aligned patient info: name + status + John Doe indicator
- Added geboortedatum (dd-mm-yyyy Dutch format)
- Added BSN extraction from FHIR identifiers
- Compact layout: Patient details | Timestamp | Actions ⋮ | Search
- Actions dropdown with "Nieuwe rapportage" (expandable)

Cleanup:
- Deleted ClientHeader component (141 lines duplicate code)
- Simplified PatientLayoutClient (only useSetPatient hook)
- Single source of truth for patient display

Result: Clean context-based architecture, improved UX, -141 LOC
