Update multiple files

[openminddev]

This pull request enhances the fall detection tracking system by adding more detailed information about detected falls, including bounding box coordinates and confidence scores. It also updates the way model engine files are referenced, improving platform compatibility.

Fall detection tracking improvements:

• The FallInfo class now includes bbox (bounding box for the detected person) and confidence (fall detection confidence score) attributes, providing more context for each fall event.
• When matching falls to faces, the bbox and confidence values are now populated for each FallInfo instance.
• The output dictionary now includes a new fallen_now_details field, listing each fallen person with their name, bounding box, and confidence score for improved downstream processing or UI display. [1] [2]

Model engine file handling:

• The model directory path and pose engine file naming in run.py have been updated to use the correct engines directory and to select the pose model based on platform, improving compatibility across different environments.
