drop MongoDB code

MongoDB support unnecessarily complicated the code and there's no need to run distributed servers in the foreseeable future. This keeps the abstract storage interface so we can wrap a distributed cache in the future.

   * Fixed `.pdb` files ignored for error stack traces for mods rewritten by SMAPI.
 
 * For SMAPI developers:
-  * When deploying web services to a single-instance app, the MongoDB server can now be replaced with in-memory storage.
+  * Eliminated MongoDB storage in the web services, which complicated the code unnecessarily. The app still uses an abstract interface for storage, so we can wrap a distributed cache in the future if needed.
   * Merged the separate legacy redirects app on AWS into the main app on Azure.
