Looks good. Let me know when it's ready for full review.
I've never written kotlin but I have written scala once the appropriate tests have been added. This looks similar, though I'm sure some of the nuances are lost on me.

minor: If we follow the principle of least knowledge here and pass flagSize and medianAgeInDays as arguments, this function may be easier to test as we then do not need to mock/instantiate the teamFlags object to pass in.

Excuse my lack of kotlin knowledge here.
Is it possible to extract flagDetails.size / 2 like statements to meaningful variables like medianFlag here to make this code easier to digest?
Can we utilize a guard clause to reduce the cognitive complexity of this block?
