In-game capture revealed two canvas families: ScreenSpaceOverlay/
ScaleWithScreenSize (the HUD, ref 1920x1080 match=1) and WorldSpace/
ConstantPixelSize (NamePlate and friends). Unity ignores referenceResolution
in ConstantPixelSize mode, so the old HUD_SCALE knob could never affect the
in-world labels. Split into HUD_SCALE (referenceResolution) and WORLD_SCALE
(scaleFactor), applied per mode.
Also echoes the knob values and logs APPLIED lines, so a stale console edit is
immediately obvious instead of looking like the fix did nothing.
