net/frr: Improve OSPF/OSPF6 section

Important notices
Before you add a new report, we ask you kindly to acknowledge the following:

• I have read the contributing guide lines at https://github.com/opnsense/plugins/blob/master/CONTRIBUTING.md
• I have searched the existing issues, open and closed, and I'm convinced that mine is new.
• When the request is meant for an existing plugin, I've added its name to the title.

Is your feature request related to a problem? Please describe.
OSPF has some configuration options that could be at the wrong places, or cancel each other out. This makes the plugin a bit hard to configure and potentially confusing.

Describe the solution you'd like
Stay as closely as possible to the configuration possible in the manual page:
https://docs.frrouting.org/en/latest/ospfd.html

• Finalize Area tab
• Move area specific options from interfaces/networks etc... to the Area tab
• Move passive interfaces to the interface tab
• Order Tabs from most important to least important
• Fix how Prefix Lists and Route Maps are referenced (right now you have to create the same Prefix List Name multiple times to add items to the same prefix list, but then only take one of those to reference all of the same named ones it in the Route Map or other spots, very confusing) https://github.com/opnsense/plugins/issues/5457
• Possibly more things that we don't know yet, implicit magic should be pulled out and made explicit.

Describe alternatives you've considered
Will take a few iterations most likely and has potential to cause regressions.
