Introduces an exportOrdersToCSV function in lib/api-client.ts to allow exporting orders by status as a CSV file. Updates various UI components to use the '•' (bullet) symbol instead of '·' (middle dot) and replaces some emoji/unicode characters for improved consistency and compatibility. Also normalizes the 'use client' directive to include a BOM in many files.
Updated audio playback and preloading logic to check for and handle returned promises from play() and load() methods. This prevents uncaught promise rejections in browsers where these methods may return undefined, improving reliability and error handling for notification sounds.
Added an AudioPreloader React component to preload the /hohoho.mp3 audio file for notifications, and included it in the app layout. Also updated _document.tsx to add a preload link for the audio file. Added yt-dlp.exe binary to the repository.
