Add kilometer-based Fahrtkosten billing, self-service distance entry, role deletion

- Facility: TravelCostMode (Pauschale/ProKilometer) + TravelCostPerKm, alongside
  the existing flat rate; fixes FacilityService.UpdateAsync silently dropping all
  Konditionen fields on update.
- New EmployeeFacilityDistance (Mitarbeiter x Einrichtung -> km) with full
  office-side CRUD in omsorgapp, plus a self-service endpoint/UI so field staff
  can maintain their own commute distance via OMSORG Connect (new
  ModuleType.EmployeeFacilityDistances, Own-scope, no Facilities access needed).
- Roles can now be deleted (blocked with a 409 while still assigned to a user).
- Fix employeesApi.js missing the Date-object conversion for dateOfBirth/entryDate/
  exitDate that crashed employee creation whenever a date was filled in; add a
  clear/remove control for those date fields.
- Requirements: flesh out FR-REC-3 with a staged Akquise cadence, add FR-REC-5/6
  for CRM feature scope and success metrics.
- Regenerate api-client-ts and api-client-php for all of the above.
