usluge.datum_unosa i troskovi.datum_unosa su TEXT kolone (ne DATETIME) —
modernc.org/sqlite driver za njih vraća string, ne time.Time, pa je Scan
direktno u *time.Time pucao sa "unsupported Scan ... string into *time.Time".

Dodat parseDatumUnosa helper (ručni time.Parse), koriste ga
skenirajUslugu/skenirajTrosak umesto oslanjanja na driver auto-konverziju.
