fix: MinGW compatibility for mock HID interface tests

- Use manual copy loop instead of std::copy_n in getInputReport mock
  to work around potential MinGW std::span/copy_n interaction issues
- Cast ASSERT_EQ values to int for proper printing of uint8_t values
  (prevents null byte characters from showing as empty)
