Fix uploading drag-and-drop files on some terminals

Actually a workaround :P

ghostty and iTerm2 escape the file path before passing it to senpai.
If the file cannot be resolved, try again after un-escaping the
file path. Not great, but better than a switch on terminal ID.

Also, make sure to trim any extra newline, even if passed as Ctrl+j
(for you, ghostty!).
