[Reputation Oracle] refactor: web3service and dependent configs

[dnechay]

Issue tracking

Part of #3084

Context behind the change

• removed NetworkConfigService because it violates common approach for config services: they should work only with env vars for simplicity, no custom logic
• however, the above is not the case for Web3ConfigService.operatorAddress because we can derive this value from PK and avoid having another env var for address
• added fixtures folder: place where we going to have all generators for test data and some hardcoded stuff when it's necessary to test exact values; later we will get rid of test/constants in favor of this folder
• start to use fixtures and mock generators in common & utils & also fixed some tests there
• cleaned up how we use Nest modules:
  • do not export anything from module if it's not imported later
  • no need to import ConfigModule because we have our config exported globally
  • when you import some module, there is no need to pass what it exports in providers list
  • re-arrange imports to go as "libs", "outer modules/tools", "this module stuff"
  • the above step revealed old circular dependency, so fixed it as well

How has this been tested?

• CI tests pass
• Run locally; e2e test for auth/web3/signup endpoint to succeed
