refactor: improve code quality across controllers and services

- DRY FurniEditorController: extract duplicate try/catch blocks into handleApiError(),
  formatItemData(), buildUpdateData(), buildInsertData(), castValue() methods
- ProfileController: replace 45 lines of manual date formatting with Carbon's diffForHumans()
- Replace custom Password rule (180 lines) with Laravel's built-in Password::min() rule
- RadioController: extract RadioStreamService and RadioScheduleService, reducing from 608 to 323 lines
- Add RadioSettings enum to replace magic strings throughout radio feature
- Add CurrencyTypes::columnName() helper method
- Add consistent return types (JsonResponse, View, RedirectResponse) to all controller methods
