Fix attendance start date, history worker filter, and add Amount column

1. Attendance form: Force start date to blank by clearing Django 5.x auto-fill
   from model default (default=timezone.now). Added self.fields['date'].initial=None
   in AttendanceLogForm.__init__().

2. History list view: When filtering by a specific worker, show only that
   worker's name in the Workers column (not all workers on the log). Uses
   filtered_worker_obj passed from the view.

3. History list view: Added Amount column (admin-only) showing daily cost.
   When filtering by worker, shows that worker's daily_rate. When unfiltered,
   shows total via new WorkLog.display_amount property (sum of all workers'
   daily_rate, uses prefetch cache for efficiency).
