## Summary
In the admin panel workspace detail page, the **Upgrade Status > Last
error** row was rendering the raw `errorMessage` string directly. Long
messages (typically full stack traces) overflowed the table cell and
overlapped neighbouring rows, breaking the layout.
The `Last command` row in the same table already uses
`OverflowingTextWithTooltip` (the helper used elsewhere in settings
tables) to clamp long values to a single line and reveal the full text
in a tooltip on hover.
This PR applies the same treatment to the `Last error` row, with
`isTooltipMultiline` so newlines in the stack trace are preserved when
the tooltip opens.
## Test plan
- [ ] Open Admin Panel > a workspace with a failed upgrade and verify
the `Last error` row stays on a single line with an ellipsis
- [ ] Hover the row and verify the full multi-line error is shown in the
tooltip
- [ ] Verify other rows (Last command, Last updated, etc.) and the
workspace info section are unaffected
