header: per-route page titles + a centered, click-to-rename tab title

Each dashboard route now sets its own document.title (route→title map in
usePageTitleSync, mounted in DashboardLayout). The title also renders centered in
the top header; clicking it edits inline and updates the browser tab live —
per-tab only, reset on navigation/refresh (not persisted).
