feat(glass): make the dev tuner theme-aware (Sync to current theme)

Browse source 
The tuner writes inline vars (global), so its sliders always showed the dark/
backdrop-on baseline even when viewing light. Add a 'Sync to current theme'
button that clears the inline overrides, reads the live theme-driven values into
the sliders, and headers the Copy-CSS export for the active scope (:root for
dark, html[data-theme="light"] for light) — so light-theme glass can be dialled
in and exported straight into the right block.
