Subject: [PATCH] Phase 4: persist module config via E_Config_DD

Versioned descriptor for E_Iwd_Config with auto_connect, show_hidden,
refresh_interval and preferred_adapter; load/save against the
"module.iwd" domain. Stale or missing config falls back to defaults.
The settings dialog UI is still a stub.
