feature-233-implement-openrouter: Add removeChunksByShasum method to SupabaseRepository and integrate it into VectorActionUseCase

- Implemented a new method in SupabaseRepository to remove chunks based on their SHA256 checksum.
- Integrated the new method into VectorActionUseCase to handle cases where the number of remote chunked files differs from local chunked files, ensuring proper cleanup in Supabase.
- Enhanced logging for better tracking of chunk removal operations.
