UI

• Transcript search now supports replace, match case, and whole word options, with keyboard shortcuts and improved navigation between matches
• Search now auto-scrolls to the active result and stays in sync between transcript and editor views
• Calendar UI has improved visual hierarchy (cleaner header spacing/typography and clearer weekend styling)
• Calendar onboarding now shows a proper loading state while calendars are being fetched, and onboarding button overflow spacing has been fixed
• Fixed metadata panel scrolling behavior in session headers for more consistent layout handling
