fix: premjesti kalendar widget u Layout, popravi PDF toast i Servisi danas

- TaskCalendarPortal u Layout.astro (van AnimatedPage transforma) pa fixed
  pozicija uvijek prati viewport rub bez probijanja sadržaja
- Kalendar widgeta panel koristi clipping wrapper (overflow:hidden + animirana
  width) umjesto translate3d — potpuno skriva sjenu i border kad je zatvoren
- Serviser vidi samo svoje taskove, supervisor vidi sve; neprijavljeni korisnik
  ne vidi widget (return null)
- FleetDashboardShell sluša calendar:open-task event i otvara TaskServiceRecordsModal
- Servisi danas broji Taskove (scheduled_date=danas, status aktivan/servis)
  umjesto Servisnih zapisa
- downloadGeneratedPdfByUrl hvata grešku i prikazuje Toast (npr. PDF nije
  dostupan ili je istekao)
