🧹 Standardize little-endian conversion using shared.ToLittleEndian

[adcondev]

Standardized the little-endian conversion logic across the pkg/commands subpackages. Replaced manual & 0xFF and >> 8 bitwise operations with calls to shared.ToLittleEndian. This refactoring improves code consistency and maintainability. Verified with unit tests across all modified packages.
