Add tenant information fields to LocationEditForm

Added optional tenant fields (first name, last name, email) to billing locations
with a toggle to enable/disable 2D barcode generation for tenants.

Changes:
- Added generateTenantCode, tenantFirstName, tenantLastName, and tenantEmail
  fields to BillingLocation interface
- Updated LocationEditForm with toggle control and conditional tenant fields
- Implemented conditional validation: tenant names required when generateTenantCode is true
- Updated updateOrAddLocation action to persist tenant data across all update operations
- Added localization strings for tenant fields and validation messages (Croatian/English)

The generateTenantCode flag is persisted in the database and controls visibility
of tenant name fields. When enabled, both first and last names become mandatory.
