Describe the bug

Found will using the new event simplepie_after_init (#7007)
When processing the event, if the request to the feed fails $simplePie->status_code remains at 0 even when the logs show something like:

FreshRSS SimplePie GET 429 http://localhost:4985/custom
[admin] [Sat, 30 Nov 2024 11:59:17 -0500] [warning] --- cURL error 22: The requested URL returned error: 429 [http://localhost:4985/custom]

To Reproduce

1. Create an extension which registers to the hook simplepie_after_init and prints or does something with $simplePie->status_code
2. Update or add a feed which returns an http error (I just ran a local server to force a 429)
3. See the logs of simplepie receiving the error code, while the extension receives 0

Expected behavior

SimplePie should have the http code the request returned.

Additional context

Seems the issue is a combination of missing parts
In this section the new exception doesn't have $file->get_status_code()

Here $th->getCode() should be used instead of a hard-coded 0

Similarly here, in the catch block the code should be taken from the exception

I'm still looking into how actually the property $status_code of File is populated and where is being used to know if there are more cases which might not fill in the value of the response.
