fix: popout inherits exact theme via opener window inline styles

- Copies documentElement.style.cssText from main app (has all CSS variables from themes.js setProperty)
- This propagates ANY theme (Github, Linear, Spotify, Notion, etc.) dark+light
- Fallback: localStorage obsigate-theme + obsigate-theme-mode for direct popout access
- Removes the !important hack — replaced by proper cssText inheritance
