Reset tty1 properly when bee-boot-status exits

Add TTYReset=yes and TTYVHangup=yes so systemd restores the terminal
to a clean state before handing tty1 to getty. Without this the screen
went black with no cursor after the status display finished.

Also remove DefaultDependencies=no which was too aggressive.
