Invoice filtering should match the `greenfield api` statuses.

It’s time that we address invoice filtering statuses.

Right now, when you click on invoice filters this is what you get:

A few things:

• Paid status no longer exist, calling invoices paid is inaccurate.
• Paidwas replaced with Settled
• Drop down paid filters settled and processing

Questions:

1. Should we just use terminology that 100% matches statuses and show that
2. Should we use collared labels in dropdown so people can easier distinguish statuses?
3. Unusual is weird but very useful, any other name for this one, its’ not a status per se, but a collection of statuses that require attention?

This issue requires collaborative effort from back-end and design teams to come up with technically accurate but easy to use solutions that doesn’t introduce complex terminology and innacurate naming. pinging @NicolasDorier @dennisreimann @dstrukt @Kukks

@bolatovumar There’s no such case where the same status would map to two different colors. The example you provided is because in the legacy API indeed Confirmed and Complete were same or very similar.

We should basically reflect what we have on the invoices view.

PR number https://github.com/btcpayserver/btcpayserver/pull/4000 (4 Millenium) for your review sers.

As discussed in the thread on the issue, we are not making any color changes. We are only changing Paid to Settled as Paid no longer exists as a status.
