fix(gh): confirm a failing workflow with a different query string (#1)

GitHub can answer one exact run-listing query from an old cached result
for weeks. The same query on a new connection returned the same old
failure, so a workflow whose latest runs passed still showed as failing.

The confirmation request now adds page=1. The changed query skips the
cached result and returns current runs. The test models a cache that
serves the plain query only.
