Gonna merge this so we can start to put NewDot issues behind a beta. There's a lot of stuff on hold that we can probably start scaffolding out ASAP.

Due to an unfortunate conflict, a regression to the IOU feature was caused by this PR.

@parasharrajat's PR modified the permissions logic, removing the betas subscription from the Permissions.js file at the same time that you added a new beta flag using the existing pattern.

Steps to reproduce

• Send an IOU Request to a user with a USD personal policy currency
• Login as the user with a USD personal policy currency
• Attempt to open the IOU Details Modal

[Julesssss]

Due to the urgency of this IOU blocker, I'll raise the PR. No need to worry about this.

@Julesssss Just noticed that this causing lint check failure on other PRs.
