Subject: [PATCH] settings: add Apply button

Extracted save logic into _apply() method. Apply writes settings
and emits settings_changed without closing the dialog. Save calls
Apply then closes. Lets users preview setting changes before
committing.

behavior change: settings dialog now has Apply | Save | Cancel.
