fix(e2e): verify keyless claimed keys link href instead of following redirect

Apply the same fix from #8195 to the "claimed app with missing keys" test
and the shared testClaimedAppWithMissingKeys helper. These tests clicked
the "get keys" link and followed the redirect chain to the dashboard,
which timed out because the dashboard redirect URL pattern changed. Now
validates the href attribute directly instead.
