[yesudeep]

Description

Multiple logging middleware improvements needed for the multi-server sample:

• Log all access requests and fix duplicates
• Color-coded access requests for each server
• Show METHOD and path first, then structure
• Highlight errors in red

Location

• File: py/samples/multi-server/src/main.py
• Lines: 56-59
• Current code:

  # TODO: Logging middleware > log ALL access requests and fix dups
  # TODO: Logging middleware > access requests different color for each server
  # TODO: Logging middleware > show the METHOD and path first and then the structure
  # TODO: Logging middleware > if the response is an error code, highlight in red
  

Acceptance Criteria

• Log all access requests without duplicates
• Color-code requests by server
• Show METHOD and path prominently
• Highlight errors in red
