bug: Insurance rest endpoints documentation incorrect for patient pid

[adunsulag]

Examining the insurance rest endpoints the documentation is incorrect where it specifies a patient pid it actually uses the patient uuid (puuid). We need to clarify this in the documentation. I'd change the implementation but I'm concerned with breaking backwards compatability for anyone who read the code and coded to the broken behavior. Changing the documentation will at least make it accurate for future consumers of the endpoint.

Ending up changing the implementation AND the documentation. Fixed in this PR: #7197
