First step toward unifying all app modals on the Manage-Portfolio visual style. Add, as shared material:: helpers (additive — no caller yet, no visible change): - blur-overlay open refcount + 1-frame latch (Push/Pop/AnyBlurOverlayActive[LastFrame], LatchBlurOverlayActive) so App::render's effect guard can be modal-agnostic; - capture-frame query (IsCapturingBlurBackdrop) for scroll-fade suppression; - RightAlignX and SegmentedControl (promoted verbatim from market_tab); - BeginFadeScrollChild/EndFadeScrollChild in a dedicated overlay_scroll.h (kept out of the widely-included draw_helpers.h because effects::ScrollFadeShader's GL headers clash with SDL's in some TUs). Also fix IsCurrentWindowOverlayDialog to prefix-match "##OverlayScrim" so suffixed overlay windows are recognized by the modal-aware hover check.
