fix: proširi bilješke na članove tima i osvježi kalendar

Widget Bilješke sada omogućuje odabir više članova tima (ne samo
servisera), a backend validacija i testovi su usklađeni.

Dodatno, nakon realtime service_note notifikacije sada se osvježava
service-notes store, te create flow više ne briše lokalne bilješke kada
odgovor vrati praznu listu.
