[TM-2084] Move demographics new controller and support querying

[Scriptmatico]

This demographicData isn't the right shape. I'm a little surprised it compiles... it's been tricky getting the type safety guards right on those DTOs. It should look like this (example from the association processor that is also creating this DTO):

terramatch-microservices/apps/entity-service/src/entities/processors/association-processor.ts

Line 72 in f6ddd71

const additionalProps = { entityType: this.entityType, entityUuid: this.entityUuid };

I'm also surprised it's not complaining that model could be null. In this case, something like this should be right:

const { demographicalType: entityType, demographicalId } = demographic;
const model = LARAVEL_MODELS[entityType];
if (model == null) {
  this.logger.error('Unknown model type', entityType);
  throw new InternalServerErrorException('Unexpected demographic association type');
}
const entity = await model.findOne({ where: { id: demographicalId }, attributes: ["uuid"] });
if (entity == null) {
  this.logger.error('Demographic parent entity not found', { entityType, id: demographicalId });
  throw new NotFoundException();
}
const additionalProps = { entityType, entityUuid: entity.uuid };
const demographicDto = new DemographicDto(demographic, additionalProps);
