Show previous assignees on task card 👥

File: server/models/Task.js

No record of who previously worked
on a task 💀 fr!!

Fix: add assigneeHistory to Task model:
assigneeHistory: [{
user: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
assignedAt: { type: Date, default: Date.now }
}]

// push to history in routes/tasks.js on PUT:
if (req.body.assignee &&
req.body.assignee !== task.assignee?.toString()) {
task.assigneeHistory.push({
user: task.assignee,
assignedAt: new Date()
})
}

// show in TaskModal:
{task?.assigneeHistory?.length > 0 && (

Previously: {task.assigneeHistory.length} assignee(s)

)}
