fix(translations): Ensure missing keys display original text instead of prefixed labels (#2319)

- Added a custom `MissingTranslationHandler` in `app.module.ts` to remove `labels.catalogs.` prefix
  when a translation key is not found.
- Updated `TranslateModule` configuration to use the custom handler globally.
- Ensured that missing translations fall back to the original value.
- Removed an unnecessary change from `address-tab.component.ts` introduced in a previous PR, as the
  current implementation resolves the issue more effectively.
