fix: update documentation examples to use correct field names and explicit commands (#280)

- Fix JMESPath examples to use correct Cloud API field names (planMemoryLimit instead of memoryLimitInGb, databaseId instead of id)
- Replace all implicit smart command references with explicit cloud/enterprise prefixes
- Update example outputs to match actual API responses
- Fix all documentation to reflect removal of smart routing feature from PR #141
