* Note: Replace external tnef/opentnef shelling with Convert::TNEF for
application/ms-tnef attachments.
For root-run Webmin mailbox parsing, decode TNEF as the mailbox owner
instead of root by carrying open_user on mail objects and switching to
that user for the parser temp-file work.

Webmin now uses the bundled QRCode::Encoder implementation by default to generate TOTP QR codes locally and inline, without relying on qr.cgi or external services.
This encoder requires Perl 5.24 or newer, so qrencode is no longer included as a recommended package dependency. On older systems where the bundled encoder cannot run, admins can still install qrencode manually to restore QR generation support.
Systems old enough to lack Perl 5.24 are typically already well past their supported security lifecycle, so keeping qrencode preinstalled by default is no longer treated as a packaging requirement. When neither option is available, Webmin falls back cleanly to manual TOTP setup using the shared secret.
