Add MobSF_AI module integration

[ashishsecdev]

Describe the Pull Request

This Pull Request introduces MobSF_AI, an optional AI. assisted analysis module for MobSF using Chatbot endpoint with OpenAI.

MobSF AI enhances static analysis results by providing:
- AI driven contextual explanation of findings
- Risk prioritization suggestions
- Natural language summary of security issues
- Developer friendly remediation guidance

The goal of this module is NOT to replace MobSF’s existing detection engine but to augment the output layer with AI-assisted intelligence for better usability and faster triage.

Key Characteristics:
- Modular structure (can be enabled/disabled)
- Does not modify core scanning logic
- No impact on existing detection rules
- Designed to work post-analysis on generated reports

Architecture:
- AI processing is triggered after static analysis completion
- Consumes existing MobSF scan results (JSON)
- Generates additional enriched output section
- Keeps separation between core MobSF layer and Chatbot AI layer

This PR focuses on clean integration without affecting existing functionality.
