📝 Code Quality: Replace print statements with proper logging

[ManvithGopu13]

Logging Issues

Current Problems:

• All error/info messages use print() statements throughout the codebase
• No log levels (DEBUG, INFO, WARNING, ERROR)
• No structured logging
• Difficult to filter/search logs in production
• No log rotation or file management

Affected Files:

• main.py
• routes/image/route.py
• routes/video/video_kaggle.py
• routes/audio/audio.py
• functions/image/image_local.py
• functions/video/video_kaggle.py
• functions/audio/audio.py

Recommended Solution:

• Use Python's logging module
• Configure log levels via environment variables
• Add structured logging with context (request ID, user, etc.)
• Implement log rotation
• Use appropriate log levels for different message types
