i18n: wire statsIntro into renderer-texts + drop unused statsScannedAtNever

Two related locale-table fixes:

1. statsIntro was already defined in both DE+EN but never applied — the HTML's German static text stayed visible when the user picked English. Wired it through renderer-texts: the locale strings now include the <code>{streamer}/live/</code> / <code>{streamer}/</code> markup that the HTML carried inline, and the setText pass uses applyHtml to render them so the inline <code> styling survives. The locale strings are static developer-authored content (no untrusted input) so the inline <code> tags are safe.

2. statsScannedAtNever was defined in both DE+EN but had zero callsites — leftover from an earlier stats-card iteration. Removed.
