- Use the main display grid control to display deleted books
- Added search functionality for deleted books. This required creating a temporary search index in the `InProgress` folder. The products grid control now uses an instance of `ISearchEngine` to filter its grid entries. The main grid uses a singleton instance of `MainSearchEngine`, which merely wraps `SearchEngineCommands.Search()`. The TrashBinDialogs use `TempSearchEngine`.
- Users can now batch select `Everyting` as well as `Audible Plus Books`
Avalonia:
- Refactor main grid context menus to no longer require reflection
- Remove instance queue. This is a database, after all, and is designed to be accessed and written to concurrently
- Reduce the number of calls to DbContexts.Create()
- Ensure that no LibationContext remains open across an await boundary. Multithread context access is the most likely culprit for past issues.
- Make all Update UserDefinedItem methods asynchronous.
- Update all project runtime targets
- Update all dependencies
- NOTE: Using Npgsql.EntityFrameworkCore.PostgreSQL RTM build from MyGet
- Delete unused pubxml files (they were made redundant by recent workflow changes)
- Replace Libation.sln with Libation.slnx
