fix: guard http.DefaultTransport type assertion in xiaomi for Go 1.25 (#15787)

Browse Source 
## Problem

`TestXiaomiNewModelWithCustomDefaultTransport` panics on Go 1.25:

```
panic: interface conversion: http.RoundTripper is models.roundTripperFunc, not *http.Transport
```

In Go 1.25, `http.DefaultTransport` is no longer `*http.Transport`, so
the unchecked type assertion in `NewXiaomiModel` panics when the test
replaces it with a `roundTripperFunc`.

## Fix

Use a safe type assertion with fallback to a new `http.Transport`,
matching the pattern already used in `modelscope.go`.

## Verification

```bash
go test -run TestXiaomiNewModelWithCustomDefaultTransport ./internal/entity/models/...
# PASS
```
