fix: encode basename in restore action

[kesselb]

• Resolves: [Bug]: It is impossible to restore a file from the trashbin containing Cyrillic characters in the name #39823
• Resolves: [Bug]: "Restore" failed on some elements - String contains non ISO-8859-1 code point #39445

Summary

As per https://xhr.spec.whatwg.org/#the-setrequestheader()-method and https://infra.spec.whatwg.org/#byte-sequences the header value must be in the range 0x20 (SP) to 0x7E (~) hence we need to encode everything else.

There might be many locations where this would be needed then 🤔
