fix: resolve runtime errors and shadowed variable warnings

- use custom_minimum_size instead of minimum_size on Button (Godot 4.6 API)
- reduce module_resized signal to 3 args to match _save_layout signature
- rename testing_tile refresh param data -> _data (unused)
- rename name -> layout_name in save_layout/switch_layout (shadows Node.name)
