Refactor application context and repository structure

- Updated `AppContext` to include separate repositories for movies, reviews, diaries, and stats.
- Modified use cases to utilize the new repository structure, ensuring that the correct repositories are called for their respective operations.
- Introduced `DiaryRepository` and `StatsRepository` traits to encapsulate diary and statistics-related operations.
- Updated all relevant use cases, handlers, and tests to reflect the changes in repository usage.
- Ensured that panic repositories are updated to implement the new traits for testing purposes.
