* 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
