Bug: [Brief description of the bug] sort bug on activity time sent

[terrazoon]

Description

when I try to sort by "Time sent" on the activity page, it does not sort properly.
to repro: find a service with a lot of activity, notice the initiial sort order is random and not time sent desc as you would expect. Sort by time sent descending.
expected result: All the 2025s would come first, followed by 2024s
actual result: It looks like page one sorts, but when you flip to page 2 there will be 2025s mixed in randomly with the 2024s.
hypothesis: it is doing "page one" sorting, which is probably not what the user expects or wants.

One thing to look at - is the full result set sorted properly and accounting for paging? There might be an API response that has to be adjusted or added to support this.

Also noting that the performance of retrieving results should be the same whether you sort or not! The query under the hood that runs should handle it fine and if it doesn't, we need to check that the right indexes are setup in the table in the database.
