refactor: graphql adapter

[rot1024]

In particular, the GraphQL code was very difficult to understand, so I refactored it to make it easier to change the implementation of GraphQL resolvers.

• Unify 2 packages into internal/adapter/gql
  • internal/adapter/graphql
  • internal/graphql
• Separate packages for data loaders (gqldataloader) and models (gqlmodel)
  • Functions in gqlmodel are now public and ready to write unit tests
• "Controllers" in gql package have been abolished
  • Loaders will continue to be responsible for loading the data
  • The process of updating the data is now implemented directly in the resolvers of GraphQL
• Add asset node query
• Remove updatePropertyValue* mutations (updatePropertyValue mutation replaces them)

Note: From now on, you can use this command to generate code from the GraphQL schema: go generate ./internal/adapter/gql

just wanted to remind you that the code coverage is not so good
