[fix] Update title button tests after onMouseDown method refactor (#5082)

Fixes unit tests that failed after PR #5079 which moved title button
handling logic from LGraphNode.onMouseDown to LGraphCanvas level.

- Updated LGraphNode.titleButtons.test.ts to test canvas-level logic instead of calling node.onMouseDown() directly
- Updated LGraph.test.ts snapshot to reflect removal of onMouseDown function from node serialization
- Tests now mock button.isPointInside() and verify onTitleButtonClick() calls
- Removed unused variables to fix TypeScript compilation
