Complaint date information and fake today needs to be fixed

For complaints, at a minimum, we have three dates: occurrence date, report date, and finding date.

Currently, when we generate (predictor) features we include the incident if the occurrence date is before the fake today. If the report date (or finding date) is not also before the fake today, this information should not be included in the (predictor) features because at the point of the fake today we don't actually know that the incident occurred.

An improvement would be to only include incidents after they are reported (and/or the finding) date. This will also interact with Issue number 8 in the police-eis-private repo (referencing Nashville staging population).

Start by locating the complaint predictor-feature generation and the fake-today date filtering. Trace how occurrence, report, and finding dates are handled, and review the interaction with Issue 8 in the police-eis-private repository. Done means future report or finding information is excluded from predictor features at the fake today, with coverage for the relevant date combinations.
