Parsing HTML belongs before the data reaches the data layer, not in it. Move the
flattening to AudibleUtilities, where the rest of the Item translation lives, so
Book.Description holds plain text and DataLayer no longer references
HtmlAgilityPack.
Import now updates a description as well as creating one, which it never did
before: books imported while descriptions were stored as raw HTML are still
holding markup, and a re-scan is what clears it. A scan that reports no summary
leaves the stored one alone.
This also cleans up the CSV/Excel export, which was emitting raw HTML too.

Book.Description is publisher_summary verbatim, which is HTML. Audible's .aaxc
files embed an already-flattened copy, so the fallback only fired on Widevine
downloads - whose DASH files carry no description tags at all - and wrote raw
<p> markup into the file's comment and long-description atoms.
Move the grid's existing HtmlAgilityPack flattening into a shared helper that
also de-entitizes, and use it for the tag fallback. Extract the tag-filling body
of the RetrievedMetadata handler so it can be exercised directly by a test.

- 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.
