refactor: use getSidebar() API in inline status action

Update showStatusInlineAction to use @nextcloud/files v4 sidebar API:
- Import getSidebar() from @nextcloud/files
- Replace window.OCA.Files.Sidebar with getSidebar() proxy
- Pass node object directly to sidebar.open()
- Use sidebar.setActiveTab() to activate LibreSign tab
- Add proper availability checks and error handling
