Have a "manual balance refreshing mode"

Would be designed to reduce the account-correlation risk that comes from batching many account balance requests at once. Also reduces load on the backend!

May be a duplicate, but requested in #15169.

Might want to consider making price-refreshing a manual option too?

Should probably have these options as part of the privacy page during onboarding.

Start by reviewing the related request in issue #15169 and tracing how account balance requests, price refreshing, and the privacy page during onboarding currently work. Clarify whether manual balance refreshing alone is in scope and define the expected onboarding option and completion behavior before implementation.
