fix: Replace C-style casts with C++ static/reinterpret casts

C-style casts should be replaced with appropriate C++ cast operators
for better type safety and code clarity. This change fixes cppcheck
style warnings about C-style pointer casting by using:
- static_cast for simple pointer type conversions
- reinterpret_cast for memory buffer pointer arithmetic

The changes maintain identical functionality while following modern
C++ best practices for explicit casting.
