Fix grants/volumes test failure on azure-ucws (#4880)

## Changes

Fix
`TestAccept/bundle/resources/grants/volumes/DATABRICKS_BUNDLE_ENGINE=direct`
failing on azure-ucws.

The Azure-to-S3 URL normalization replacement in `volumes/test.toml` and
the `[METASTORE_NAME]` replacement in the root `test.toml` both had
`Order = 0`. Due to stable sort, `METASTORE_NAME` ran first — but on
Azure the storage URL is `abfss://`, not `s3://`, so it found no match.
By the time the Azure URL was normalized to
`s3://deco-uc-prod-isolated-aws-us-east-1/...`, the `METASTORE_NAME`
pass had already completed.

Fix: set `Order = -1` on the Azure URL normalization so it runs before
`METASTORE_NAME`.

## Tests

- Local acceptance tests pass
- Replacement order verified for both Azure and AWS inputs
