refactor: remove ComfyPage wrapper methods, use helpers directly

- Remove 27 deprecated/wrapper methods from ComfyPage
- Migrate callers to use helper classes directly:
  - keyboard.selectAll/bypass/undo/redo/moveUp/moveDown
  - clipboard.copy/paste
  - settings.setSetting/getSetting
  - workflow.loadWorkflow/deleteWorkflow/setupWorkflowsDirectory
  - contextMenu.clickMenuItem/clickLitegraphMenuItem
  - nodeOps.resizeNode with DefaultGraphPositions
  - canvasOps.clickEmptySpace with DefaultGraphPositions
- Replace deprecated node click methods with direct canvas clicks
- Replace position getter properties with DefaultGraphPositions imports
