v0.3.5 UI Updates & Idle CPU Load reduction

Added

• Dashboard Item Ratings: Added interactive star ratings to songs in the active session panel. Users can now view and update song ratings directly from the dashboard during practice.
• Desktop-Only View Utilities: Implemented a .desktop-only CSS utility to manage visibility of rich UI elements that are too bulky for mobile screens.
• Production Server (Gunicorn): Integrated Gunicorn as the production WSGI server for Docker deployments, significantly improving stability and resource management.

Changed

• Statistics Visual Consistency:
  • Replaced the default Chart.js legend in the Category Breakdown chart with a custom, list-based legend in the same style as the Top Practiced Items card.
  • Improved grid alignment on the Statistics page to ensure cards don't stretch unevenly when content sizes differ.
• Responsive Layout Polishing:
  • Adjusted the width of practice items' time display to ensure metadata like "(100%)" fits on a single line.
  • Simplified margin and padding in the Category Breakdown card for a more balanced look.
• Docker Optimization: Optimized Docker image and runtime configuration to reduce idle CPU usage by over 90% by disabling filesystem reloader polling in production.

Fixed

• Statistics Padding: Resolved an issue with excessive bottom padding in the Category Breakdown card.
• Star Rating Persistence: Ensured ratings updated from the dashboard are immediately saved to the library database and persistent across sessions.
• Idle CPU Load: Fixed high CPU usage in Docker environments caused by the Flask development reloader.
