refactor: sync from template - ENABLE/DISABLE macro pattern

Browse Source 
- board_config.h: replace #define/#undef with ENABLE/DISABLE constants
- All debug switches use ENABLE/DISABLE instead of define/undef
- Replace #ifdef with #if MACRO == ENABLE across all sources
- Sync updated README documentation
