The single Copy button left it on the user to format a message and
get the code into Discord/email. Added a layout that makes sharing
obvious:
- QR encodes the join code text so a friend with a phone can scan
the host's screen and forward the code without typing it
- "Copy as message" formats a one-line "Join {server} on DorkNet!
Download at github.com/... and paste this code:" pitch
- "Email to friend" opens the default mail client with subject +
body prefilled, code in the body
- QR built via QRCoder -> WriteableBitmap directly (no
System.Drawing dependency); palette matches the launcher
