feat(03-02): navigation restructure, TotalsBar refactor, and setup hooks

- Move collection view from / to /collection with gear/planning tabs
- Rewrite / as dashboard with three summary cards (Collection, Planning, Setups)
- Refactor TotalsBar to accept optional stats/linkTo/title props
- Create DashboardCard component for dashboard summary cards
- Create useSetups hooks (CRUD + sync/remove item mutations)
- Update __root.tsx with route-aware TotalsBar, FAB visibility, resolve navigation
- Add item picker and setup delete UI state to uiStore
- Invalidate setups queries on item update/delete for stale data prevention
- Update routeTree.gen.ts with new collection/setups routes
