feat: add standalone task detail page for Android widget deep-links

Adds GET /task?id=xxx&source=xxx route that renders a full mobile-friendly
task detail page (session-protected). Widget task rows now open this page
when tapped. HandleUpdateTask redirects back to the page after a non-HTMX
save. Android: threads serverUrl through composable chain to TaskRow.
