What is the current behavior?

Currently, there are several issues with message handling in MQTTX:

1. Messages are lost when sending at high rates
2. Message rendering becomes out of order at high frequencies
3. Unable to load new messages when scrolling up/down
4. UI performance degrades significantly with high message rates
5. No optimization for different message rates scenarios

Issue Number: #1614 #1770

What is the new behavior?

This PR introduces several improvements to message handling and rendering:

1. Message Integrity

   • Fixed message loss during high-frequency publishing
   • Ensured correct message sequencing
   • Implemented reliable message storage and retrieval

2. Scroll and Load Optimization

   • Fixed issues with loading previous/next messages while scrolling
   • Improved scroll performance
   • Added proper scroll position maintenance

3. Dynamic Buffer System

   • Added automatic buffer mode for high message rates (>30 msgs/sec)
   • Implemented batch rendering for better performance
   • Smooth transitions between normal and buffer modes
   • No message loss during mode switches

4. Performance Improvements

   • Reduced UI rendering pressure
   • Better memory usage
   • Improved overall responsiveness
   • Optimized message processing pipeline

Does this PR introduce a breaking change?

• Yes
• No

Specific Instructions

1. Testing high-frequency scenarios:

   • Test with different message rates (5/s, 20/s, 50/s)
   • Verify message integrity during rate changes
   • Check scroll behavior with large message volumes

2. Key improvements to verify:

   • No message loss at any rate
   • Correct message ordering
   • Smooth scrolling experience
   • UI responsiveness under load
   • Buffer mode activation/deactivation
