fix: Correct printf format specifiers for unsigned integers

This commit addresses cppcheck warnings about mismatched printf format
specifiers (invalidPrintfArgType_sint). The format specifiers %i and %d
expect signed integers (int) but the variables being passed are unsigned
integers (uint32_t, unsigned). This mismatch can lead to undefined behavior
and incorrect output formatting.

Changes made:
- utils/kmstouch.cpp: Changed %i to %u for event code formatting
- utils/kmstouch.cpp: Changed %d to %u for event type and property type formatting
- utils/kmsview.cpp: Changed %d to %u for frame number formatting

These fixes ensure proper type safety in printf formatting and prevent
potential undefined behavior when printing unsigned integer values.
