Refactor dashboard sections: KPI cards, filters, fallbacks

- Replace 4 static KPI cards with 5 interactive cards
  - 'Otvoreni nalozi' and 'Servisi danas' are now clickable links
  - Added context-aware subtotals (u kontekstu) when crane context is set
  - Replaced 'Upozorenja' (mileage-based, irrelevant for cranes) with 'Bez putnog naloga'
  - 'Dovrseni nalozi' now shows completion percentage
  - Added new card 'Moji zadaci danas' (tasks assigned to current user, today)
- Added crane context filter toggle on the tasks table (Sve dizalice / Odabrani kontekst)
- Service records page now shows last 10 records as fallback when no crane context is selected
- Moved SyncLogPanel into a collapsible <details> element
- Removed dead code: PAGE_MODE_TO_SECTION, activeSection/setActiveSection state,
  navbar:navigate event handler, and DashboardTopbar nav tab block (showSectionNav
  was always false; navigation is handled by Navbar.jsx)
