refactor(CodeEditor): update Panel tests to use default context functions

- Removed the use of mockPanelFunctions in Panel tests, replacing them with defaultPanelContextFunctions for improved clarity and consistency.
- Updated test cases to directly utilize context configuration for undo and redo actions, enhancing maintainability and readability of the tests.
