Business Dashboard UI: analyze and update FFs to use reactive getter

#### Description

Business Dahboard UI is making extensive use of `getStoredFlag`, which is intended for FFs that only need to be checked once:

For flags that should be reactive (ie, can flag change after the page loads due to some dynamic thing?), `getFeatureFlag` should be used instead.

Analysis is needed to determine which flags can safely be fetched using getStoredFlag vs getFeatureFlag. And then, implement any changes.

#### Impact

It's possible some FFs are not reactive when they should be. This means that, if a FF is changed while a user is already using the Business Dashboard UI then either a feature won't be enabled right away when it could be, or a feature won't be disabled right away when it should be.
