Comprehensive Test Suite for Enkrypt Secure MCP Gateway Tools

Tests all 7 gateway tools:
1. enkrypt_list_all_servers
2. enkrypt_get_server_info
3. enkrypt_discover_all_tools
4. enkrypt_secure_call_tools
5. enkrypt_get_cache_status
6. enkrypt_clear_cache
7. enkrypt_get_timeout_metrics

Includes tests for:
- Basic functionality
- Guardrails (input/output)
- OAuth integration
- Caching behavior
- Timeout handling
- Error scenarios
- Security testing with bad_mcps
