refactor(frontend): simplify imports and update syntax for wizard steps and delay durations

- Consolidated `material3` imports in `CreateBewerbWizardScreen` and `TurnierBewerbeTab` for cleaner code.
- Switched `WizardStep.values()` to `WizardStep.entries.toTypedArray()` for improved readability.
- Changed `kotlinx.coroutines.delay` argument to use `Duration.milliseconds` for enhanced clarity and type safety.
