fix(repeater): restore node name at top of home screen

A merge conflict resolution collapsed the `// node name` comment and its
`_display->setCursor(0, 0)` call onto a single line, which commented out
the cursor reset. The node name then rendered at whatever cursor position
was left over from the previous frame (the end of the IP: line), so it
trailed the IP address and wrapped onto the next line instead of appearing
at the top of the home screen.

Split the comment and setCursor back onto separate lines so the name is
drawn at (0, 0) again.
