feat(web): IA-3 navigation, legacy redirects and top-bar inbox (FE-1)

Sidebar becomes 5 groups (overview / resources / subscriptions / organize /
system). Pending items move to a top-bar inbox with badge and grouped
dropdown. Engine panel, schedules and identity pages redirect to the task
page, its plan tab and media overview views; the download plan becomes a
second tab of the download panel. nav.test and smoke cover the new routes.
