Site-level billing: Wrap remaining routes in React Error boundaries and log errors

This is a follow-up to https://github.com/Automattic/wp-calypso/issues/46432 which intends to wrap one route in site-level billing inside a React Error Boundary.

This has worked really well in Checkout for finding unexpected bugs. We should start at the top-level components that we added for site-level billing management.

Read follow-up issue #46432 first, then locate the top-level components added for site-level billing management and identify the remaining routes. Confirm each route is wrapped in a React Error Boundary and that errors are logged consistently across the site-level billing flow.
