Add "Copy cell content" option to table cell context menu

[Heivir]

Scope & Context
This ticket is about adding an option to copy the cell value directly to the clipboard from the context menu when right-clicking on a table record.

Current behavior
Right-clicking on a record cell opens a context menu displaying record-level actions (such as Delete, Add to Favorites, Export, and More actions), but does not offer any option to copy the specific cell's content.

Expected behavior
When right-clicking on any cell in a table view:

The context menu displays an additional "Copy" (or "Copy cell content") action.

Clicking this option copies the plain text value of the target cell directly to the clipboard.

A brief toast notification confirms the action (e.g., "Copied to clipboard").

Technical inputs
Update the table record context menu component to retrieve the targeted field value based on the clicked cell.

Add a "Copy" MenuItem to the dropdown menu list.

Use navigator.clipboard.writeText() to write the cell's formatted value to the user's clipboard.

Dispatch a workspace toast notification upon successful copy.
