* feat(web-shell): add cell value dialog on double-click in markdown tables
Double-clicking a table cell opens a modal dialog showing the cell's full
content with copy and close actions. The dialog clears any active selection
or row details on open, supports Escape to dismiss, and click-outside to
close. Adds EN/ZH i18n keys and four unit tests covering open, copy,
dismiss, and state-clearing behaviour.

* fix(web-shell): portal table cell dialog
* fix(web-shell): block shortcuts behind cell dialog
