Store both original unrotated pesData and uploaded rotated pesData in cache
to ensure exact consistency on resume and prevent issues from algorithm changes
between versions. This fixes rotation/position reset issues after page reload.
- Cache original unrotated pattern + rotation angle for editing
- Cache exact uploaded pattern data sent to machine
- Restore original offset after loading cached pattern
- Use cached uploaded data on resume instead of recalculating

Removed redundant patternUploaded state from PatternStore and replaced
it with a derived selector usePatternUploaded() in MachineStore that
computes it from patternInfo !== null.
This eliminates duplicate state, removes the need for synchronization
logic, and ensures a single source of truth for pattern upload status.
Updated all components (App, LeftSidebar, FileUpload, PatternCanvas,
WorkflowStepper) to use the derived selector.

Extracted App.tsx (469 lines → 91 lines) into 5 new components:
- ErrorPopover: Displays error details with solutions (84 lines)
- AppHeader: Machine status, workflow stepper, errors (207 lines)
- ConnectionPrompt: Connect button or browser warning (67 lines)
- LeftSidebar: Conditional rendering of controls (42 lines)
- PatternPreviewPlaceholder: Empty state for preview (46 lines)
This improves code organization, maintainability, and reusability.
Each component now has a single, clear responsibility.
