feat(market): bump the portfolio backdrop blur radius (64) via sole-consumer isolation

Browse Source 
Raising the backdrop radius alone would thrash the shared radius-keyed blur cache (the
glass panels blur at ~30). Instead, while a full-window blur overlay is active, glass
panels use their opaque fallback (IsFullWindowBlurOverlayActive) — they're covered by the
backdrop anyway — so the backdrop is the SOLE applyBlur caller and can use a strong custom
radius (64) with the cache staying coherent and frozen. The flag is toggled alongside the
theme-effect suppression by a RAII guard in App::render().
