feat: Enhance DungeonCanvasViewer with Object Outline Filters and Context Menu Improvements

- Added a sub-menu for toggling visibility of object outlines based on type and layer, allowing for more granular control over displayed objects in the dungeon canvas.
- Implemented checkboxes for filtering object outlines by type (Type 1, Type 2, Type 3) and layer (Layer 0, Layer 1, Layer 2) in the debug menu.
- Updated the drawing logic to respect the new filtering options, ensuring only the selected objects are rendered on the canvas.
- Improved the visibility of object ID labels by making them smaller and less obtrusive, enhancing the overall clarity of the canvas display.
