🎨 fix(theme): align UI controls with global radius tokens

Remove hard-coded and capped border radius overrides so shared controls and feature actions consistently follow the active theme radius.

- Replace fixed radius utilities with semantic theme-aware radius tokens
- Remove redundant `rounded-full` and pixel-based overrides from header, toolbar, Playground, and utility actions
- Drop unused `StatusBadge` rounded prop usage
- Keep existing component behavior intact while improving global theme consistency
