Handle Enum/IntEnum in _format_value, fix README namespace description

- Add Enum handling before int check in _format_value (IntEnum is a
  subclass of int, so str(IntEnum.VAL) gives the name not the value)
- Add unit tests for IntEnum and str Enum formatting
- Fix README namespaces row to include OData queries under records

 | **Context Manager** | Use `with DataverseClient(...) as client:` for automatic cleanup and HTTP connection pooling |
-| **Namespaces** | Operations are organized into `client.records` (CRUD), `client.query` (QueryBuilder & SQL), `client.tables` (metadata), and `client.files` (file uploads) |

 | **Records** | Dataverse records represented as Python dictionaries with column schema names |
 | **Schema names** | Use table schema names (`"account"`, `"new_MyTestTable"`) and column schema names (`"name"`, `"new_MyTestColumn"`). See: [Table definitions in Microsoft Dataverse](https://learn.microsoft.com/en-us/power-apps/developer/data-platform/entity-metadata) |
