Describe the bug

No leases are being shown in the Services, DHCPv6, then the Leases tab. This was working under the previous version just before 23.7

To Reproduce

Steps to reproduce the behavior:

1. Configure DHCPv6 to give leases for an interface. For example:

2. Go to Services, DHCPv6, then the Leases tab
3. Notice there ar no leases shown:

4. Login into the OPNsense host as root and then select 8) Shell
5. Change to the /var/dhcpd/var/db directory.
6. Display the dhcp6.leases file and notice there are leases:

root@opnsense:/var/dhcpd/var/db # cat dhcpd6.leases
# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-4.4.3-P1

# authoring-byte-order entry is generated, DO NOT DELETE
authoring-byte-order little-endian;

Expected behavior

Display the leases in the Services, DHCPv6, Leases tab.

Describe alternatives you considered

See steps 4. through 6. above but not ideal. I would expect most system admins not to know where to dig.

See above.
