Redesign job details panel as slide-in sheet for better MES UX

Convert the operation details modal from a Dialog to a right-side Sheet
panel with compact, MES-optimized layout:

- Use Sheet component sliding from right (600px width)
- Fixed header with operation name, job/part info, and cell badge
- Time info bar (estimated/actual/remaining) always visible at top
- Scrollable content area for all details
- Fixed footer with action buttons (start/stop timing, complete, report issue)
- Compact spacing following design system guidelines
- Glass card styling with backdrop blur
- Proper overflow handling - no more content spilling outside visible area
