feat(python): expose materialized view auto-refresh creation options (#4621)

Expose optional `auto_refresh_enabled` and
`auto_refresh_interval_seconds` when creating materialized views from
Python and Rust. Omitted intervals remain unset: the server determines
when to refresh.

```python
view = db.create_materialized_view(
    "recent_orders", "orders",
    auto_refresh_enabled=True,
    auto_refresh_interval_seconds=300,
)
```

## Architecture and workflow

- Python synchronous, asynchronous, job-returning and namespace wrappers
forward both optional values through PyO3 to the Rust creation builder.
Both default to `None`; no client interval is selected.
- Remote creation calls `POST /v1/materialized_view/{id}/create` with
the defining query and only the supplied refresh properties. A `202
Accepted` response must contain a job ID. Existing job tracking waits
for the server's ordinary SQL CREATE job before synchronous creation
opens the view.
- The server validates and authorizes the CREATE, then uses the existing
SQL worker to populate the view and persist its refresh settings. The
Lance agent subsequently uses those settings to submit REFRESH SQL jobs.
- Explicit positive finite fractional seconds are preserved. An interval
alone does not enable refresh. Embedded connections retain manual
refresh, accept explicit disabled state, and reject requests for
automatic scheduling rather than ignore them.

Includes API documentation and coverage for omission, false,
fractional/invalid intervals, namespace forwarding, server job IDs and
invalid acceptance responses.

Requires the server REST-create endpoint to be deployed before SDK
release. Existing remote `with_no_data=True` remains unsupported.

 ## Materialized Views (Synchronous)
 
+On Cloud and Enterprise, creation accepts `auto_refresh_enabled` and
+`auto_refresh_interval_seconds`:
+
+```python
+view = db.create_materialized_view(
+    "recent_orders",
+    "orders",
+    auto_refresh_enabled=True,
+    auto_refresh_interval_seconds=300,
+)
+```
+
+Omit `auto_refresh_interval_seconds` to let the server determine when to refresh.
+These options also apply to asynchronous creation and creation jobs. Embedded
+connections support manual refresh and reject automatic scheduling requests.
