Non-ASCII mailbox names are now encoded as modified UTF-7 (RFC 3501, section 5.1.3), so they can be passed as an ordinary str. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Mailbox names are now encoded as modified UTF-7 (RFC 3501, section 5.1.3), so an international mailbox name can be passed to any command as an ordinary
str.For backward compatibility, a
strthat is already valid modified UTF-7 — for example a name obtained from a rawLISTresponse and decoded as ASCII — is sent unchanged, and abytesargument is sent verbatim (bypassing encoding), so existing code keeps working. UnderUTF8=ACCEPT, mailbox names are sent as UTF-8 instead.This builds on the
utf-7-imapcodec added in gh-66788.
