The page had no visual signal that it configures a third-party channel, so it read like any other Accounted setting. Adds an inline-SVG WhatsApp mark next to the section title and on the button that opens WhatsApp (replacing the generic lucide chat bubble, which was standing in for a logo it is not). Inline SVG rather than a bundled asset: no network request, scales, and survives the CSP. SettingsSectionHeader gains an optional `mark` slot; every other settings tab is untouched and stays mark-less on purpose, so the rail does not turn into a sticker album. The green is the one place brand colour appears in settings, which matches the design rule that colour belongs to actors rather than chrome.
