Fix APIKey in search resolver for get role (#16540)

Fixes https://github.com/twentyhq/twenty/issues/16534

Typing was wrong, apiKey from request object is ApiKeyEntity and not a
string which was then failing when using
```typescript
const roleId = apiKeyRoleMap[apiKeyId];

    if (!isDefined(roleId)) {
      throw new ApiKeyException(
        `API key ${apiKeyId} has no role assigned`,
        ApiKeyExceptionCode.API_KEY_NO_ROLE_ASSIGNED,
      );
    }
```

error
```
API key [object Object] has no role assigned"
```
