Make lastStatusTime mandatory in 200 responses of the status APIs

[eric-murray]

What type of PR is this?

• enhancement/feature

What this PR does / why we need it:

lastStatusTime is an optional parameter in the 200 responses of the status APIs. But there is no good reason not to include this parameter. Otherwise, there is the risk of ambiguity as to whether the returned status is still valid. It should be mandatory for any status that is not current, and the simplest way to enforce that is to make it mandatory for all responses.

Which issue(s) this PR fixes:

Fixes #138

Special notes for reviewers:

Could be part of Spring'25 meta-release if approved and merged today

Is this PR meant for Spring25?

It could be a solution to #138, which is tagged Spring25. But there may not be time to agree and merge this before the Sping25 release, in which case it will have to wait.

Changing a reponse property from optional to required is a breaking change, we'll need to have this into consideration for Fall25, specially for roaming and reachability which are already in stable v1.0

It's not a breaking change for the client, so a "v1" client will still work, even with this change
