Settings for the server are now combined with the settings from the SDK. This introduces a large breaking change and a migration should be created. This refactor utilizes .NET Configuration and the Options pattern. This will allow for the overriding of any setting using envionment variables. It also means that Settings.yml can be used to override any .NET configuration. A SettingsProvider implementation was created, and any updating of settings was changed from SettingsService.SaveSettings() to SettingsProvider.Update(s => { ... })
Ref #190
Ported the save API functionality to endpoints as part of ongoing efforts to use minimal API patterns.
Added some more security checks to make sure users can only alter or download their own saves.
Moved upload pathing to use the default save storage location. Settings pages will need to be updated to use this storage location. Other areas of the application will have to be checked to make sure they're not reading from `Settings.yml`.
