Fix: Multiple UI and functionality improvements

Fixed all reported issues:

1. **Dark Mode Improvements:**
   - Fixed bulk-actions-info white on white text (now yellow on dark background)
   - Fixed timeline-content boxes with explicit dark mode colors
   - All text now properly visible in dark mode

2. **Dashboard Enhancement:**
   - Added "Assigned To" column showing ticket assignments
   - Updated TicketModel query to include assigned user information
   - Shows "Unassigned" when no user assigned

3. **Removed Ticket View Tracking:**
   - Removed logTicketView call from TicketController
   - Created migration 011 to delete all view records from audit_log
   - Viewing tickets no longer clutters activity timeline

4. **Removed Duplicate Status Dropdown:**
   - Removed status field from hamburger menu
   - Status can now only be changed via the workflow-validated dropdown in ticket header
   - Prevents confusion and ensures all status changes follow workflow rules

All changes improve usability and reduce clutter.
