Show assignee name on hover over avatar

File: client/src/components/Board/TaskCard.jsx

The avatar circle shows initials like "AK" but
hovering shows nothing — you don't know whose it is!

Fix: just add a title attribute:
// BEFORE

{task.assignee.name[0].toUpperCase()}
// AFTER

{task.assignee.name[0].toUpperCase()}
1 word change!! Native browser tooltip,
zero packages needed! 🎯

Hi @anoopcodehack I would like to work on this issue and add the assignee name tooltip on avatar hover. Please assign it to me.
