feat: add clipboard import support for table component (#8846)

* feat: add clipboard import support for table component

Add support for pasting TSV (Excel/Sheets) and Markdown table data directly into table components. The component now detects clipboard data format and automatically parses rows when pasting.

* [autofix.ci] apply automated fixes

* ✨ (TableNodeComponent/index.tsx): Improve parsing functionality for TSV and markdown tables to handle different scenarios and edge cases
🔧 (table-node-component.test.tsx): Add tests for TableNodeComponent to ensure proper functionality and edge case handling
