fix(moysklad): add User-Agent header + enable HTTP auto-decompression

Browse source 
Two issues surfaced after the previous gzip-removal:
1. MoySklad's nginx edge returned 415 on some requests without a User-Agent.
   Send a friendly UA string (food-market/0.1 + repo URL).
2. Previous fix dropped gzip support entirely; re-enable it properly by
   configuring AutomaticDecompression on the typed HttpClient's primary
   handler via AddHttpClient.ConfigurePrimaryHttpMessageHandler. Now the
   response body is transparently decompressed before the JSON deserializer
   sees it — no more 0x1F errors.
