Agent V3 Tuning

[shankar-vision-eng]

Adding minor prompt tuning to make sure test cases run without any errors

• The tester code sometimes picks up the file name from user instruction and some times it does not. Its not reliable even with prompt tuning
• So added the image path explicitly to the prompt this way tester LLM always uses an actual image for testing
• Disabled outer reflection and made it optional. Will be replaced by Human reflection
• bbox distance needs to be in pixels so added denormalize to that function
• Return results dictionary for both call and chat_wtih_workflow functions
• Added debug line to code prompt so that when tests execute it returns results from the tools
