analytics(deeplink): route report notification tap to its report (KC-51 ph4c)

Completes deep-link routing (goal #7): AnalyticsDeepLink is Identifiable; a
tapped weekly/monthly report notification is consumed in ContentView on
launch/active and presents AnalyticsView opened to that area. Core round-trip
re-verified standalone; SwiftUI wiring needs an Xcode build.

+- `AnalyticsDeepLink` now `Identifiable` (id = url string) → usable with
+  `.sheet(item:)`. Round-trip re-verified standalone.
+- Notification tap → stores pending link (delegate) → `ContentView` consumes it on
+  launch + `.active` → presents `AnalyticsView(initialLink:)` opened to the
+  weekly/monthly area. Completes goal condition #7 (report notifications
+  deep-link to their report). Wiring not build-verified (SwiftUI/app deps).
