Fix Redis connection type conversion bug

- Fix set_redis_config_from_cli to preserve correct types for Redis connection parameters
- Keep port and db as integers, ssl and cluster_mode as booleans
- This resolves the issue where uvx commands would hang due to Redis connection failures
- Re-enable Redis connection ping test in CLI

Fixes issue where 'uvx --from /path redis-mcp-server --url redis://localhost:6379/0'
would not show 'Starting the Redis MCP Server' message due to connection hanging.
