Subject: [PATCH] fix(table_core): Show pending values from RowEditBuffer in
 render

Fix Tab showing empty cell after editing:
- Add edit_buffer field to DrawRowsConfig
- drawRowsWithDataSource now checks RowEditBuffer before DataSource
- VirtualAdvancedTable passes row_edit_buffer to render

Priority: RowEditBuffer (user typed) > DataSource (DB/memory)
