Better MS XDR

Adds some visual tweaks to the Microsoft Defender XDR UI.

Better MS XDR supercharges the Microsoft Defender XDR incidents queue at security.microsoft.com with features that Microsoft hasn't built in - all without leaving the portal. ↕️ Sortable columns - Click any column header to sort the incidents list by Incident ID, Name, Severity, Status, Top Risk, First Event Time, Last Event Time, or Last Update Time. Click again to reverse the sort, and once more to clear it. Sorting works correctly with Fluent UI's virtual scrolling - no rows get lost as you scroll. 🪚 Compact mode - Reduce row height to fit more incidents on screen at once — ideal for high-volume queues or smaller displays. 🕯️ Dim resolved incidents - Resolved incidents are visually de-emphasized so your attention stays on what's active. 🌕 Dark mode toggle - Switch the XDR portal between light and dark themes instantly from the toolbar popup or the in-page banner — no need to dig through portal settings. 🙈 Hide the page header - Reclaim vertical screen space by hiding the incidents page header with a single toggle. 🔝 Scroll-to-top button - A floating button appears when you scroll down, letting you jump back to the top of the list instantly. 🎛️ Inline controls - All toggles are accessible directly from a compact banner injected into the page header - no need to open the popup for quick adjustments.
