The Software Updates page opens with every row checked, so one click on Ignore selected packages ignores the updates of every package, for all versions, with no confirmation. The page then shows its empty state. Undoing it means removing the packages one by one in Manage ignored updates, or resetting the whole list. Uninstalling several packages already asks for confirmation (#5533).

• Confirmation: when more than one package is checked, the button opens the same dialog as the uninstall confirmation: "Are you sure?", "Do you really want to ignore updates for the following {0} packages?", the list of packages, Yes / No. Nothing is ignored until Yes is clicked.
• With a single package checked, the behaviour is unchanged.
• The Installed Packages page has the same button and gets the same check.
• The body of the uninstall dialog becomes a shared PackageListConfirmationDialog; the uninstall confirmation itself is unchanged.

One new string, added to lang_en.json only, for the community to translate as usual. Build, dotnet format whitespace and style, and the translation validation scripts pass. Rendered headless on macOS, light and dark, on the Software Updates page with 40 checked updates: the before/after captures are attached to the Jira ticket.
