fix: update tier dropdown text assertions in LLMD mock test (#6044)

The test was expecting 'All resource tiers', 'No resource tiers', and
'Specific resource tiers' but the component uses 'All tiers', 'No tiers',
and 'Specific tiers'. Updated both the page object helper and test assertions
to match the actual component labels.
