Refactor annotation tools and implement quality choice annotation feature

- Updated the annotation label from "bewertet" to "annotiert" in the HomePage component.
- Removed the SingleChoiceView component and replaced it with a new QualityChoiceEntryView component for handling quality choice annotations.
- Introduced QualityChoiceView component to manage the flow of quality choice annotations, including navigation and progress tracking.
- Updated EditableExperimentHeader to default to 'quality-choice' annotation tool.
- Added unique index for annotations in the database schema to prevent duplicate entries.
- Enhanced WaveformPlayer to support audio playback state management.
