fix(drone-dep): ADV-drone-02 — teardown fallback when SSO enrichment fails after deploy

When _enrich_deps_with_sso raises after deploy_deps succeeds (e.g., gitea API
call fails), deps_state stays {} and the finally block's `if deps_state:` guard
skips teardown, orphaning the dep at its deterministic domain.

Fix: add an `else` branch after the `if deps_state:` block that reads
$CCCI_DEPS_FILE (the legacy-list written by deploy_deps) and calls
teardown_deps on the cold entries so no dep is left running.

Unit tests: test_load_run_state_provides_fallback_for_enrichment_failure and
test_fallback_skips_warm_entries verify the data-flow that the fallback relies on.
19/19 unit tests pass.
