fix: Resolve userSettings is null error in worker

This commit fixes the "userSettings is null" error that occurred in the worker when trying to join or create a game.

- Introduced IUserSettings interface to define the contract for user settings used in the worker.

- Updated UserSettings class to implement IUserSettings and provide a getData() method for serialization.

- Modified WorkerMessages to include serialized user settings in the InitMessage.

- Passed user settings from ClientGameRunner to WorkerClient, and then to the worker.

- Updated createGameRunner to accept IUserSettings and pass it to getConfig.

- Corrected type inconsistencies across various configuration and theme classes to align with IUserSettings.

- Re-added missing imports in relevant files.
