Filename not URL decoded when using Safari

[baobao1270]

Describe the bug When downloading a file from Tencent COS (private write/read bucket) on Safari, the filename is url-encoded like %E4%BE%8B%E5%AD%90.zip, instead of 例子.zip. Firefox on macOS, Firefox on Windows and Chrome on Windows does not have the bug.

To Reproduce Steps to reproduce the behavior:

1. Configure the Cloudreve with a Tencent COS (private write/read bucket) storage
2. Upload a file with Chinese character in its name
3. Download it on Safari
4. See error

Expected behavior The Cloudreve handle the filename correctly

Desktop (please complete the following information):

• OS: macOS 13.0.1
• Browser: Safari
• Version 16.1 (18614.2.9.1.12)

Additional context Cloudreve passes the response-content-disposition URL param to COS. The param is url-encoded, COS will decode it and response it as Content-Disposition header. However, different browser has different behavior on this header. That is the cause of bug.

On Chrome/Firefox, Cloudreve's behavior is correct. They accepts the Content-Disposition header like Content-Disposition: attachment; filename="%E4%BE%8B%E5%AD%90.zip".

However, on Safari, it works different. It only accepts the header like Content-Disposition: attachment; filename="例子.zip"

I think Cloudreve should determine the browser based on user agent, and pass response-content-disposition for different browsers.

The Internet Explorer's behavior is more weird. I don't want to research on IE for it is too old and even Microsoft is abandoning it.
