Make balanced smart context option the default (#1186)

 ## Summary by cubic Set “balanced” as the default smart context mode. Users now get balanced when Smart Files Context is enabled and no mode is set; “conservative” must be explicitly selected. - **Refactors** - Default fallback to balanced in UI and engine (proSmartContextOption undefined -> "balanced"). - ProModeSelector saves "conservative" explicitly; selector reads undefined as balanced. - Updated schema and types to allow "balanced" | "conservative". - Engine payload now includes smart_context_mode with "balanced" by default; e2e tests and snapshots updated. - **Migration** - No action needed. Existing users without an explicit mode will use balanced by default; selecting conservative persists.
