Mouthwash Overhaul Kit Receipt (Biospecimen)

[Davinkjohnson]

(Low priority)

-This is largely copied from the package receipt flow, which was improved before Home Collections implementation

-Amber has already done the essential work on the Firestore side, ensuring database operations are all-pass or all-fail.

@amber-emmes probably plan for this in Nov as well as it's lower priority.
