Consolidated Analytics Pages and Copy Retrospective to Markdown

This FireHydrant update consolidates analytics pages into a single "MTTX Analytics" tab for improved reporting and real-time visibility, and sunsets older pages on March 31, 2026. Additionally, users can now easily copy retrospective reports as markdown for quick sharing, alongside several improvements to API permissions, heartbeats, bug fixes, and usability across the platform. These changes aim to streamline incident management and enhance the user experience within FireHydrant.
