feature: add new filter to bulding search

[kamilfedio]

#97
I added the filters mentioned and improve graphql&model of bulidings

good work. I have one proposition of a simple refactor.

[simon-the-shark]

it stopped being easily readable at this point and I would strongly recomend some refactor to divide this into smaller logically separated pieces.

so you can do this in many ways, but my personal proposition would be:

in map view config file

abstract class BuildingSearchConfig {
  static const buildingCodeSeparator = "-";
}

then create util file, example location: lib\features\buildings_map\utils.dart

extension ContainsCaseUnsensitive on String? {
  bool containsUnsensitive(String str) {
    if (this == null) return false;
    return this!.toLowerCase().contains(str.toLowerCase());
  }

bool containsBuildingCode(String buildingCode) {
    if (buildingCode.contains(BuildingSearchConfig.buildingCodeSeparator)) {
      return containsUnsensitive(buildingCode);
    }
    return this
            ?.replaceAll(BuildingSearchConfig.buildingCodeSeparator, "")
            .containsUnsensitive(buildingCode) ??
        false;
  }
}

and the usage would be:

  @override
  bool filterMethod(BuildingModel item, String filterStr) {
    return item.name.containsBuildingCode(filterStr) ||
        item.addres.containsUnsensitive(filterStr) ||
        item.naturalName.containsUnsensitive(filterStr);
  }

it's just a proposition, you can refactor it in some other way you find suitable. Also I hope I haven't broken the logic :)
