feat: Allow /xldev to disable Safe Mode (#2166)

- Adds new menu item to /xldev to disable Safe Mode, allowing users to load plugins again.
  - Safe mode cannot be re-enabled once disabled.
- Add new ModuleLog.Create<T> for eventual ILogger magic
- Make safe mode writable
- Remove redundant check in CheckPolicy
