Fix numpy serialization and add comprehensive error logging
Some checks failed
Validate / validate (push) Failing after 9s
Details

Browse Source 
Server fixes:
- Fix numpy uint8 JSON serialization by converting to Python int
- Change WLED payload to flat array format [r,g,b,r,g,b,...]
- Add payload debugging logs (size, LED count, sample data)

Web UI improvements:
- Add comprehensive console logging for device errors
- Log actual error messages from state.errors array
- Log device operations (start/stop/add) with details
- Fix password field form validation warning

The HTTP API may have payload size limitations for large LED counts.
Consider UDP protocols (DDP/E1.31) for better real-time performance.
