feat(v2): remove old dashboard, add vitae + resizable windows

- Removed old Recharts dashboard view entirely (no more viewMode
  toggle, DashboardView lazy import, Ctrl+D shortcut)
- Recharts chunk eliminated from build — bundle size reduced
- Player Dashboard window: added Vitae column (red when > 0%)
- ALL windows now resizable: drag bottom-right corner handle
  (min 300×200px). Subtle diagonal line grip indicator.
- Sidebar: removed 📊 Dashboard toggle link, removed broken
  /quest-status.html external link (replaced by 📜 Quests window)
