feat(news): take ownership of the news widget from nc-vue

[SudoThijn]

The renderer in nc-vue could not fetch a feed. It read a consumer-supplied
itemsEndpoint, and LaunchPad was the only app that ever supplied one — so in
every other app the form collected feed URLs that nothing could load, and the
widget sat there empty with no error. The feed path is entirely ours already:
NewsWidgetService, FeedRefreshService, the feed cache table and its background
job. The widget belongs with them.

LaunchPad already had its own NewsWidget.vue — 617 lines, still passing its
spec, orphaned when the communal CnNewsWidget superseded it. Revived rather
than porting a second copy: it calls our own endpoint directly. The form had no
local equivalent, so CnNewsWidgetForm is ported as NewsWidgetForm, moved to the
launchpad translation domain and to this repo's lint conventions.

news is now registered in widgetRegistry.js alongside clock/weather, after
the shared-catalog import so it replaces the communal entry while nc-vue still
ships one. The content shape is unchanged, so placements authored against the
communal form keep rendering.

The itemsEndpoint injection in widgetDataAdapters.js is dropped — the
renderer owns its endpoint now, and leaving it would bind an unused function
onto the root element. Comments in WidgetRenderer and ContainerChild that
described that seam updated with it.
