Pull Request Overview

This PR migrates Arduino-specific API calls to note-c abstraction functions for better code consistency and maintainability across different platforms. The changes replace direct Arduino function calls with their note-c counterparts while maintaining the same functionality.

• Replaced ::millis() calls with NoteGetMs() for time measurement
• Replaced ::delay() calls with NoteDelayMs() for delays
• Updated include structure to use "Notecard.h" instead of "NoteDefines.h"
