get_observations_as_timeseries not order in time

[peterdudfield]

I tried getting some gsp observation data, and I noticed that sometimes it wasnt return in time order

This was when I pulled the data from 2025-12-10 to 2025-12-14 for gsp_id 100. For observer pvlive_in_day

• TODO: check there is an order by in sql query.

If this is not possible, I can put the order by in the API
