Implement a sanity checker that checks that the information stored in
the DB corresponds the chain for which the app is run. If the app is run
for one chain, and the DB contains data for another chain, the sanity
checker prevents the app from start and throws the error.

Rename the `findOneById` method of the `SRModuleStorageService` to
`findOneByModuleId`.

Replace the internal `CURATED_MODULE_ADDRESSES_FOR_CHAINS` constant with
curated module addresses with the appropriate
`REGISTRY_CONTRACT_ADDRESSES` constant from `@lido-nestjs` repo.

Remove unnecessary `consensusProviderService` variable and fix lint
errors in unit tests for `NetworkValidation` service.

Move checking that the network ID specified in .env config matches the
EL chain ID one level up in the `validate` method of the
`NetworkValidation` service.

Move checking that chain ID from the config, EL chain ID and CL chain ID
match each other to the separate `checkChainIdMismatch` private method
of the `NetworkValidation` service.

Add two new custom error types (`ChainMismatchError` and
`InconsistentDataInDBError`) with properties that help better indicate
specific of the error. Update test cases to make sure that correct error
types with correct properties are returned in each test case.

Rename `dbKey` local constant to `dbKeys`;
Rename `dbOperator` local constant to `dbOperators`.

Add new specific error types for cases when keys or operators table is
empty. Change error messages to better reflect the essence of the error.
Add new tests for testing these new error types.

Fix test that tests the case when chain ID and EL ID don't match each
other. This test should not depend on the value of the
`VALIDATOR_REGISTRY_ENABLE` env variable.
