refactor: Enhance OverworldEditor with Dynamic Context Menu and Tile Selector Widget

- Replaced static context menu setup in OverworldEditor with dynamic configuration based on the current map state, improving usability and responsiveness.
- Introduced TileSelectorWidget for better tile selection management, allowing for a more intuitive user experience when selecting tiles.
- Updated canvas controls to include zoom in and zoom out functionalities, enhancing the editor's navigation capabilities.
- Cleaned up legacy context menu code and improved overall organization for better maintainability and clarity.
