fix(tools): verify that the end date is later than the start date

[michael-desmond]

Which issue(s) does this pull-request address?

If the llm uses the openMeteo tool with a startDate in the future, but does not specify an endDate then the endDate is set to now which is prior to the start date. This causes the the service to throw an error.

Description

Check of the end data is prior to the start date, if so reset the end date.
