Premium Analytics: Authors widget follow-ups

[Nikschavan]

Fixes WOOA7S-1495

Proposed changes

Follow-ups to the Authors widget added in #49570:

• Date range from URL, not a shadowed copy. render.tsx no longer passes attributes into WidgetRoot. The host injects a reportParams into the widget's attributes, and WidgetRoot would prefer that stale shadow copy over the live URL search params the date picker writes — so the date picker never reached the query. Dropping the prop lets WidgetRoot resolve report params from the URL the same way the other Stats widgets do. The widget's own max attribute is forwarded to the inner component instead.
• Localize the untracked-authors sentinel. The Stats sanitizer substitutes an untranslated "Untracked Authors" sentinel for authors with no name. getAuthorLabel now matches that sentinel (and any empty label) and returns the localized __( 'Untracked authors' ) string. Added a test covering this.
• Type the widget attributes. Introduced an exported AuthorsAttributes type in widget.ts and composed the render-only shape (AuthorsRenderAttributes) from it plus Partial<ReportParamsFieldAttributes>, instead of redeclaring an ad-hoc inline type. Also corrected the example attribute max from the string '7' to the number 7.
• Center the chart empty state. Added margin-inline: auto so the empty state centers horizontally.

Does this pull request change what data or activity we track or use?

No.

Testing instructions

• Build/serve Premium Analytics and open a Stats dashboard with the Authors widget.
• Change the dashboard date range via the date picker and confirm the Authors widget refetches and updates (previously it stayed stuck on the initial range).
• Confirm authors with no name render as a localized "Untracked authors" label.
• Confirm the chart empty state (no data) is horizontally centered.
• Run the unit tests for the widget:
  • pnpm --filter ... test or run build-top-authors-data.test.ts to confirm the untracked-authors localization test passes.

That could be good or bad, depending on the situation. Everything covered before, and still is? Great! Nothing was covered before? Not so great. 🤷

Thanks for the follow-up fixes. This lines up with the Locations/Devices widget direction by keeping the render attributes passed into WidgetRoot and letting WidgetRoot handle the report params fallback. I left one non-blocking wording nit on the comment, but the implementation looks good to me.
