feat: non-individual entity UI improvements — hide individual-only sections, fix legal form display, send extended fields to API

- Hide Family Members tab/section for non-individual entities in client view, create flow, and preview
- Hide Financial & Classification section for non-individual entities in personal data and preview
- Fix legal form column in clients list — fetch legalForm from client API for correct display
- Add person/business icon before client name in list rows
- Remove unsupportedNpd filter — send authorizedSignatory, additionalInfo, dateOfRegistration to API
- Add registration number format hint (mat-hint) based on constitution type
- Add spacing between verification row and constitution type dropdowns
- Reduce table cell padding and prevent action buttons from being clipped
- Add missing MPL-2.0 license headers
