fix: surface the fundamentals cache result on every SEC job outcome

The runtime message only appended the cache summary when the import itself
completed. On a deferred, failed or source-locked run Admin → Jobs showed just
the import outcome, so an operator had no signal that `fundamental_data` had
advanced — contradicting the claim now made in the docstring, the schedule hint
and the deployment doc.

The import status still varies and stays the headline; the cache summary is
appended to all of them. Adds a source-locked regression test.
