feat(BA-2964): Premium price UI with fixes

[stevieraykatz]

What changed? Why?

We missed two things in #2691

1. The return value from nameExpires can be 0n for names that aren't registered. This is falsy and incorrectly tripped up the error catching logic for !result.
2. The contract read loading state wasn't properly handled leading to async failures where isLoading was true and therefore causing the same error catching on result to correctly throw for a falsy value.

This pr addresses both issues and moves the error logging out of the hook by returning the loading and error states from the hook. Consumers now check for loading and error states and act accordingly.
