[UBP] Personal usage is hard to reach or discover, and hard to differentiate from team usage pages

[jldec]

The personal usage page can currently only be reached throught the personal usage-based billing settings page.

suggestions

1. Add "Usage" back into the personal settings menu under Billing (only for feature flagged UBP users) - see image below.
2. Differentiate the usage page main heading to say either "Personal Usage" or "Team Usage"

FYI, here is an alternative UX proposal from Slack (internal):

For the navigation, I would remove the menu entry for usage in the settings, so that we can only navigate there from the button on the billing page. We could add a "<- back to settings" link on top if you think that is necessary. 🅰️ would also mean we need the selector for the individual account again. 🅱️ wastes screen estate, which will be very precious in future versions of the usage view.

If we really need a top-level menu entry for personal usage it should go under the context menu on the avatar not settings.
