Implement DioPlayerApiClient with real HTTP bodies for core API methods (oa)

Replace UnimplementedError stubs with concrete Dio calls for bootstrap, login,
logout, listSets, browseSet, listMedia, getMedia, streamMedia, downloadMedia,
getThumbnail, healthz, and readyz. Wire DioPlayerApiClient into the Riverpod
provider. Add http_mock_adapter dev dependency and 25 unit tests covering
success + error paths for all implemented methods.

+// Unit tests for DioPlayerApiClient.
+//
+// Tests use http_mock_adapter's DioAdapter to intercept Dio requests and return
+// canned JSON responses without a real network connection. This keeps tests
+// fast, hermetic, and free from platform dependencies (no OS keychain, no
+// NavigatorKey, no real server).
+//
+// Coverage: login, listMedia, getMedia (success + error cases for each), plus
+// smoke tests for bootstrap, logout, listSets, browseSet, healthz, readyz,
+// streamMedia, downloadMedia, and getThumbnail.
