[BUG] Should_list_appconfig_accounts live test fails to find appconfig account

### Describe the bug

Our live test for `appconfig_account_list` asserts that the array of returned appconfig accounts contains one with a name matching our test run's "ResourceBaseName". Plenty of resource names are returned in the list, but the resource we just deployed doesn't appear to be in it.

https://github.com/Microsoft/mcp/blob/main/tools/Azure.Mcp.Tools.AppConfig/tests/Azure.Mcp.Tools.AppConfig.LiveTests/AppConfigCommandTests.cs#L68

### Expected behavior

The test passes

### Actual behavior

The test fails to find a resource with a name matching our ResourceBaseName

### Reproduction Steps

Run `mcp - pullrequest - live` or `mcp - Azure.Mcp.Server` with live tests enabled.

The test failed with:
```
Assert.Contains() Failure: Filter not matched in collection
Collection: [{"name":" <5 or 6 long json entries> ···]
```
Maybe we're getting a paged result?
