Implement comprehensive GDPR/SOX compliance improvements and fix routing issues

- Fix README documentation links and add prerequisites warning
- Remove get_server_details from allowed MCP tools in agent.py
- Fix currenttime MCP server routing by updating path and proxy_pass_url
- Implement comprehensive GDPR/SOX compliance in auth_server/server.py:
  * Add utility functions for PII masking and anonymization
  * Hash usernames in all log outputs for privacy protection
  * Anonymize IP addresses (last octet masking)
  * Mask sensitive IDs (User Pool, Client IDs)
  * Protect JWT tokens from exposure in logs
  * Move sensitive headers to DEBUG level with masking
- Add SECURITY.md with vulnerability reporting procedures
- Create compliance documentation and gap analysis
- Ensure production-ready privacy protection while maintaining audit trail

Resolves MCP server 404 routing issues and establishes strong foundation
for regulatory compliance requirements.
