📋 Description
JIRA ID: AMM-1927
🎯 Summary
This PR transforms the CORS implementation from an overly restrictive, maintenance-heavy configuration to a secure, environment-aware, and developer-friendly approach. By removing endpoint-specific restrictions and fixing critical security vulnerabilities, we achieve:
Better Security: Environment-controlled origins, no hardcoded localhost, immutable configuration
Simpler Code: No endpoint-specific configuration, reduced maintenance
Proper Architecture: CORS handles browser security, endpoints handle authorization
Standard Compliance: Full REST API support including PATCH method
Result: A production-safe, maintainable CORS implementation that follows security best practices and reduces operational overhead.
