Fix PlayerApiClient const constructor and Media.tags deserialization (d9+e9)

- Remove const from PlayerApiClient constructor (Uri is not const-constructable)
- Replace .cast<String>() with .whereType<String>().toList() in Media.fromJson
  to silently drop non-string and null tag elements instead of throwing TypeError
- Add regression test: tags [1, 'valid', null] deserialized as ['valid']
