Fix typo

Update the GUI page for the DHCP6 server, add a if statement that prevents throwing range errors on interface that have no static IPv6 address.
It is entirely valid to operate a DHCP6 server just for prefix delegation, but ISC doesn't appear to allow it yet.

Do not skip displaying outbound NAT rules with no interface or an invalid interface; it interferes with editing/deleting the skipped rule itself or rules after it.

Revert "Use get_Cofnigured_interface_with_descr() here since that's the purpose"

This reverts commit 0c8e9f0c26b29f57faa2ccef9a559774103fee79.

Use get_Cofnigured_interface_with_descr() here since that's the purpose

Fix outbound NAT rules when interface is deleted:

- When delete interface, do not touch outbound NAT rules
- Skip outbound NAT rules when interface doesn't exist
- Bump latest_config to 9.2
- Since rules with no interface were considered as wan, convert old...

Cleanup unused pages that was supposed for upload_progress bars

This is needed since preload is now gone

Always commit the session fast to allow other consumers to proceed to their requests. This unbreaks now the lock up the GUI had allowing only one action from same source per time. Now even if you run a command that blocks indefinitely for example the GUI want lock anymore but allow you to proceed to other actions

Select default interface when WAN is disabled

If WAN is disabled, then the Traffic Graph does not default to a valid interface when it first displays. This fix selects the first valid interface if WAN is not there.
e.g. at one site there used to be 2 ISPs, on WAN and OPT1. Now the ISP on WAN has been turned off, and the interface marked disabled. The default gateway etc is all on OPT1. After a bit of history at a site, it can happen like this that WAN is disabled in the config.
