Can you repeat the test but make odhcpd more verbose by setting the loglevel to 7 (uci set dhcp.odhcpd.loglevel=7) ?
IPv6 wise the behavior seems ok as the traces indicate the dslite interface is coming up; there's a public IPv6 prefix assigned to the lan.

Can you also add the output of ip route show and ip addr show ?
