set last prebob filing date

### Replace_With_Short_Descriptive_Name
## Description:
- update colin-api, data-loader, legal-api and UI for lastPreBobFilingDate
- this date is needed in the UI because it is the actual 'minDate' for agm (since we can't recreate the state of their business before this time, but we can after it once we have history loaded in)
