T25: Timestamp tracking + izveštaj prikaz u overlay modalu

1. Timestamp: svaki potez taska (move/run) dodaje red u tabelu
   "## Vremena" u task fajlu sa događajem i vremenom.
2. Izveštaj: klik "Izveštaj" na done tasku otvara overlay modal
   sa goldmark-renderovanim reportom. Ako nema reporta, prikazuje
   sam task sadržaj.
