follow-up to #8041

static IPv6 leases are not always matched, e.g. "Reserve IP" is clickable although the lease is statically defined.

Actual behaviour

• Define lease either through Status-Overview-Reserve IP or Network-DHCP-Leases
• Lease is static defined
• Still "Reserve IP" is clickable.

Expected behaviour

Reserve IP is no longer clickable for a static defined lease.
For the same host, IPv4 is working.

Steps to reproduce

What browsers do you see the problem on?

Firefox

Relevant log output

Reserving the IP through `Status-Overview-Reserve IP` sets the DUID UPPERCASE%IAID lowercase.
Reserving the IP through `Network-DHCP-Leases` sets the DUID%IAID as lowercase.

Works for other hosts, but not this particular one.

manually setting `option duid 'xxx'` if setting through leases

`ubus call luci-rpc getDHCPLeases` shows the DUID with lowercase and IAID with lowercase.
