MoreCast 2.0: Select weather model by date

As a weather forecaster I need the ability to select the weather model for each specific date in my forecast range so that I can use one model for dates in the near future, and a different model for dates further into the future.

**Acceptance Criteria**
- [ ] UI to select weather model by date
- [ ] Given I change a model for a specific date, that datagrid updates with values from that model for that date for each station

**Definition of Done**
https://github.com/bcgov/wps/wiki/Definition-of-Done

The issue names no files or tests, so start by locating the forecast-range weather-model selector and station datagrid in the repository, then trace how a selected model supplies values for each date. Done means the UI supports a model choice per date and changing one date updates that date's station values with the selected model.
