Staging check exit code 1 (C9a/C9b). Live inspection inside orchestrator-staging
proves the production webhook handler is correct: get_project_states(SANDBOX).in_progress
= 84a76f65..., but scripts/staging_check.py hardcodes the enduro fallback b873d9eb...
=> handler correctly classifies the webhook as "no pipeline action". Fix belongs in
scripts/staging_check.py (resolve SANDBOX in_progress dynamically), NOT in handle_status_start
or any ORCH-058 image-freshness code. Image under test = ORCH-058 merge commit 094b5e2f.
