Fix DebuggerMiddleware crash on BinaryFileResponse

[ganyicz]

The scenario

Using Blaze in a project that serves BinaryFileResponse responses (e.g. Flux asset routes).

The problem

DebuggerMiddleware calls $response->status(), which doesn't exist on BinaryFileResponse.

The solution

Use $response->getStatusCode() instead — available on all response types.

Fixes #123
