[HOLD for payment 2024-11-20] [A/B Testing][Combined Track Submit] Define logic for displaying test to half of users

[grgia]

Show combinedTrackSubmit to 1/2 of all users

So we would take this off beta, and write the logic such that when either global create or the create menu from a chat (or room) is clicked - all even numbered account IDs always see Create Expense and all odd numbered see Track and Submit per usual. We don’t need any of the NVPs as I can just use funnels in Full story.

Thinking we just remove the beta and then add the even/odd logic here instead- we could even create a new Permissions file for handling all the logic for future A/B tests.

Can you discuss your proposed solution in #engineering-chat tomorrow and make sure we're not missing anything? Then we can move forward with this. I just don't know enough to spot if there's any concerns with this route.
