Fix bug where deleting a cached pattern prevented re-uploading because
the filename was lost. After deletion, the pattern remains visible in
the UI for re-editing and re-uploading, but the upload would silently
fail because displayFileName was empty.
The issue occurred because:
1. Pattern loaded from cache uses resumeFileName (from hook)
2. Local fileName state in FileUpload was never set (empty string)
3. After deletion, resumeFileName is cleared to null
4. displayFileName becomes empty, preventing upload
Solution:
- Add fallback to 'pattern.pes' when pesDataProp exists but no filename
- This ensures re-upload works after deletion while keeping pattern visible
- Pattern data (pesData) persists in App.tsx state for re-editing
Now users can delete a cached pattern and immediately re-upload it
with position adjustments or other modifications.

Add proper Heroicon components to display status indicators in the
Machine Connection panel. The icons were referenced but not rendered,
causing weird padding next to status text.
Changes:
- Import CheckCircleIcon, BoltIcon, PauseCircleIcon, ExclamationTriangleIcon
- Create stateIcons mapping from iconName to Heroicon components
- Fix reference from stateVisual.icon (doesn't exist) to stateVisual.iconName
- Render icon component dynamically based on machine state
Icon mapping:
- ready/complete: CheckCircle (✓)
- active: Bolt (lightning)
- waiting/interrupted: PauseCircle
- error: ExclamationTriangle
This fixes the TypeScript error and displays proper status indicators.

Implement support for fetching and displaying the machine's cumulative
stitch statistics using the SERVICE_COUNT (0x0100) command.
The SERVICE_COUNT command returns two uint32 values:
- serviceCount: Cumulative service counter
- totalCount: Total stitches sewn by the machine (lifetime)
Changes:
- Add serviceCount and totalCount fields to MachineInfo interface
- Implement getServiceCount() method in BrotherPP1Service
- Call getServiceCount() when fetching machine info on connect
- Display "Total Stitches" in Machine Connection panel
- Format stitch count with locale-specific thousand separators
- Handle errors gracefully if SERVICE_COUNT command fails
The total stitch count is now visible in the Machine Connection section,
providing users with insight into their machine's lifetime usage.

Change the Machine Connection panel to show the serial number instead
of the model number. The serial number is more useful for identifying
specific machines, especially when multiple machines of the same model
are in use.

Remove the redundant "Upload Complete!" green banner that appeared at
the bottom of the Pattern File section. The top blue banner "Pattern
uploaded successfully!" already provides this information along with
additional context about the locked state.
This eliminates visual clutter and duplicate messaging while keeping
the more informative message that explains the pattern is locked.

Correct the encoding of TRIM commands to use the proper bit flag (bit 1)
instead of incorrectly treating them the same as JUMP commands (bit 0).
The PEN format uses two separate flags in the Y-coordinate low byte:
- Bit 0 (0x01): FEED_DATA - Jump stitch (move without stitching)
- Bit 1 (0x02): CUT_DATA - Trim/cut thread command
Previously, both JUMP and TRIM commands were encoded with bit 0, which
prevented the machine from distinguishing between jumps and thread cuts.
Changes:
- Add PEN_CUT_DATA constant (0x02) for TRIM commands
- Update encoding logic to set bit 0 for JUMP (cmd=1)
- Update encoding logic to set bit 1 for TRIM (cmd=2)
- Add detailed comments explaining the PEN format flags
- Document that Y-coordinate flags can be combined
- Document that X-coordinate flags are mutually exclusive
This fix ensures thread cutting happens when intended, matching the
behavior of the original C# implementation in the Asura app.

Fix UI delay issue where buttons remained clickable during BLE communication
setup. Now provides instant visual feedback when operations begin.
Changes:
- Add isUploading and isDeleting state tracking in useBrotherMachine hook
- Set loading states immediately on button click, before BLE communication
- Update FileUpload component to disable upload button and show spinner

preventing double-clicks and providing clear feedback during the initial
BLE setup period before progress reporting begins.
