Make sure the plots only use "latest versions" from LAPIS

[fengelniederhammer]

We have some LAPIS instances that are backed by a Loculus instance. The ingress potentially generates new versions (revisions) of some accessions. We need to make sure that we filter out non-latest versions properly:

• Either by setting LAPIS filters accordingly
  • Advantage: Easy to implement
  • Disadvantage: All users of the LAPIS instances need to be aware that this is necessary.
• Or by filtering out non-latest versions before they get into SILO
  • Advantage: client-friendly - no user needs to think about Loculus interna (which we actually want to hide)
  • Disadvantage: maybe a bit tedious in implementation, as we need to modify the link between Loculus backend and SILO preprocessing.

Since we plan to use a Pathoplexus LAPIS, we decided to set a filter in the dashboards.

Make sure to also filter out revocation versions.
