feature-request: Menu tab for forwarding history

[hieblmi]

It might be nice to view the output of lncli fwdinghistory in a separate tab in addition to the live Routing tab. This would allow to display historic forwarding information. The start/end times could be set via config flag.

This feature complements the real-time routing event tab with historical settled routing events without storing additional data.

Might be a little simplified once this is merged to lnd: lightningnetwork/lnd#7001

I am working on this and should have a PR ready soon.

nice feature, was an option to save these kind off information into a database to go back in time and also analyze the information lntop captures with other tools already discussed ?

[hieblmi]

The discussion was started here #68 but hasn't gained traction so far.

In this PR I want to introduce a simple view of the forwarding history without the need for additional storage.
If needed this can be replaced later on by custom data extracted from the routing events.

I got the basic functionality working locally but I would like to wait until lightningnetwork/lnd#7083 makes it into the next release. This will simplify the code in this PR.
