Issue:
staging status in server mode download 
When downloading an OFFLINE product in server mode, use min values for `wait` and `time` and return a 202 status until product is available

Pull request description:
feat[server]: offline products order handling
When downloading an OFFLINE product in server mode:

- return HTTP Status 202 with new download link containing order status check information as query parameters
- don't retry to download the product again

Closes #871 

Also fixes missing `dataset` parameter after `BuildSearchResult` search-by-id in server mode
