[INT-020] int: Add API endpoint deprecation strategy
- Created DeprecationInfo structure for managing deprecation metadata - Enhanced DeprecationWarning middleware with custom deprecation information support - Added standardized deprecation headers (Deprecated, Sunset, Link per RFC 8594) - Added X-API-* custom headers for compatibility - Created MarkEndpointDeprecated helper for easy endpoint deprecation - System provides clear warnings, sunset dates, and migration guidance Files modified: - veza-backend-api/internal/middleware/general.go - VEZA_COMPLETE_MVP_TODOLIST.json
