Subject: Widget: wrap the web dashboard in a WebView (DashboardActivity)

First cut per the 2026-08-06 feasibility check (verdict: easy, no
architecture blockers): a plain WebView pointed at the configured
server URL, cookie jar enabled for the existing session-cookie login
(internal/auth/middleware.go's RequireAuth) -- no separate auth bridge
needed, the widget's own bearer token is a completely different scheme
and doesn't need to touch this at all. External links (e.g. a calendar
event's source URL) escape to the user's real browser instead of
getting stuck in the WebView.

No deep-linking to specific tabs, no native-rendered chrome -- this is
the minimal first step to validate the wrapped experience is worth
building further, not the final shape.
