Pull request overview

Refactors several UI screens to migrate away from deprecated View.SYSTEM_UI_FLAG_* fullscreen/layout flags and toward WindowInsets/WindowCompat-based edge-to-edge and system bar control.

Changes:

• Replace manual systemUiVisibility flag manipulation with SystemUIManager.hideSystemUI/showSystemUI in WebFragment custom view flow.
• Switch share/blur activities to WindowCompat.setDecorFitsSystemWindows(window, false) for edge-to-edge layout.
• Update TextPreviewActivity to hide system UI using WindowInsetsControllerCompat instead of deprecated flags.

DepositShareActivity now opts into edge-to-edge via setDecorFitsSystemWindows(false), but it no longer overrides BaseActivity’s default SystemUIManager.setSafePadding(... bg_white). This likely reintroduces an opaque (theme) background strip behind the status/navigation bars on this blur/overlay screen. Consider calling SystemUIManager.setSafePadding(window, Color.TRANSPARENT) (as MarketShareActivity/AvatarActivity do) or otherwise ensuring the insets area stays transparent to preserve the blurred background.
