Add Overworld accessors and enhance testing framework

- Introduced new methods in `Controller`, `EditorManager`, and `OverworldEditor` to access the `Overworld` instance, improving modularity and interaction with the overworld data.
- Added `GetTile` method in `Overworld` to retrieve tile data based on coordinates, enhancing functionality for tile manipulation.
- Implemented a new testing framework with automated GUI tests, including `CanvasSelectionTest` and `FrameworkSmokeTest`, to validate user interactions and ensure robustness.
- Updated `CMakeLists.txt` to include new test files and dependencies, streamlining the build process for testing.
- Refactored logging behavior to ensure proper file handling during logging operations, improving reliability in logging outputs.
