[HOLD for payment 2024-10-24] De-dupe `OpenApp` requests.

[roryabraham]

Problem

We are seeing some scenarios where multiple OpenApp requests are serialized in a row. When multiple such requests are sent, it's redundant, slows down the app, and contributes to server traffic.

Solution

De-dupe OpenApp requests such that only one can be serialized at a time.
