  • The saver kept only the id (Create(id)), dropping elevationSources and
    attributionRules; it now saves all three.
  • The controllers reported their default (Streets) to the state when the
    change listener was attached, so the state's design -- passed in or
    restored after a rotation -- turned into Streets. The controller is now
    seeded with the state's design first, and setMapDesignType records it.
  • Device round-trip test.

After a configuration change (screen rotation) the map state now keeps its design (id, style, attribution rules), uiSettings and camera paddings. Depends on android-sdk-core MapViewStateBundle; merge order core → compose → providers. Verified by rotating a Lenovo tablet (HA26Z6JL); instrumented tests pass the saved Bundle through a real Parcel.
