Fixed field name mismatch causing colors to display incorrectly:
- Frontend uses 'bojaHex' while backend expects 'boja_hex'
- Added bidirectional field transformation in API service layer
- Ensures hex color codes are properly saved and retrieved
- Also prevents editing of Bambu Lab predefined color hex codes
