[chooser] Fix screen resolution false positives

CRepresentationChooserDefault::CheckResolution() compared the
user-configured resolution limit (m_screenWidth) against the actual
physical hardware resolution (m_screenCurrentWidth), resulting in
perpetual false positives every 10 seconds. Dedicated tracking
variables (m_screenLastWidth, m_screenLastHeight) now correctly
isolate physical window resize detection from the addon's maximum
quality configuration limits.
