feat: auto-odabir i datum u dropdownu putnih naloga za taskove

- TaskCreateModal: auto-pretselektira jedini otvoreni nalog za danas pri otvaranju modala
- Dropdown labele prikazuju datum naloga i oznacavaju danasnji nalog sa zvjezdicom (★)
- Dodana napomena da vise taskova moze dijeliti isti putni nalog
- TaskServiceRecordsModal: danasnji nalozi sortirani na vrh liste
- Datum prikazan u dropdownu i u prikazu trenutno odabranog naloga
