fix(tests): align test_llm_connector with new factory + fail-fast (#179 review)

The PR rewrote collect_all() to call the new
create_extractor_from_env_or_config() helper, but the existing tests
still mocked the old direct create_extractor() symbol and the old
silent-skip-on-missing-config behavior. Five tests in
TestCorporateMemoryCollector and one in TestCollectorExtractorIntegration
were red on the PR branch.

Changes:
- Tests now mock connectors.llm.create_extractor_from_env_or_config
  (the symbol the collector imports lazily).
- Renamed test_collect_all_no_ai_config_skips ->
  test_collect_all_no_ai_config_or_env_raises and
  test_collector_handles_invalid_config -> test_collector_raises_on_invalid_config.
  Both assert pytest.raises(ValueError) — the explicit fail-fast
  semantics defect 5 of #176 was supposed to enforce.
- collect_all() no longer swallows the factory's ValueError into
  stats["errors"]; it propagates so the scheduler / admin endpoint
  surface the actionable misconfiguration message instead of
  pretending the run was a no-op.
- /api/admin/run-corporate-memory translates the propagated ValueError
  into a 500 with the factory's message, matching
  /api/admin/run-verification-detector.
