fix: shlex.quote values in as_curl() so the command is valid and not injectable

Browse Source 
header/body/url/proxy values were wrapped in raw single quotes, so a value containing a quote or shell metacharacter produced a broken or injectable command. every interpolated value is now shell-quoted.
