Logging Enhancements (#1521)

* Recreated Kavita Logging with Serilog instead of Default. This needs to be move out of the appsettings now, to allow auto updater to patch.

* Refactored the code to be completely configured via Code rather than appsettings.json. This is a required step for Auto Updating.

* Added in the ability to send logs directly to the UI only for users on the log route. Stopping implementation as Alerts page will handle the rest of the implementation.

* Fixed up the backup service to not rely on Config from appsettings.json

* Tweaked the Logging levels available

* Moved everything over to File-scoped namespaces

* Moved everything over to File-scoped namespaces

* Code cleanup, removed an old migration and changed so debug logging doesn't print sensitive db data

* Removed dead code
