Gabriel Radureau 434be7488d fix(ops): sandbox refresh-from-prod actually restores now (pg_restore -U + self-heal pause)
refresh-from-prod was structurally broken and silently no-op'd the restore:

1. pg_restore lacked -U, so the postgres image connected as its OS user `root`
   and auth-failed. The failure was swallowed by `|| echo "ignorable warnings"`,
   so the script reported success while the DROP OWNED had already emptied the DB.
   E2's original seed was a manual process, so this path had never really run.
   Fix: pass `-h $PGHOST -U $SB_PGUSER`; don't trust pg_restore's exit code (it
   returns non-zero on the harmless "schema public already exists" notice) — verify
   by counting restored llx_* tables and FAIL the Job if < 250.

2. erp-sandbox is ArgoCD-managed with self-heal ON, which reverts the
   `kubectl scale --replicas=0` within seconds — so the seed ran with Dolibarr
   still connected. Fix: pause self-heal for the duration, re-arm it after; app
   restore + self-heal restoration + secret cleanup are guarded by an EXIT trap so
   an interrupt can't strand the sandbox at replicas=0 / self-heal off.

Validated end-to-end on the live sandbox: 295 llx tables, company=Arcodange,
owner=erp_sandbox_role, self-heal re-armed, pod 1/1. README documents the self-heal
pause and the iso-prod consequence (ai_agent_sandbox is wiped → re-provision).

# sandbox-lifecycle.sh — seed / refresh the erp-sandbox Dolibarr from prod, and
# sync its uploaded documents, with prod integrity guaranteed structurally.
#
# Implements ADR-0003 (factory vibe/ADR/0003-sandbox-state-lifecycle.md):
# - prod is read ONLY (pg_dump runs in a default_transaction_read_only session);
# - the restore writes ONLY to erp-sandbox, using the sandbox's own dynamic
# credentials (a member of erp_sandbox_role, which owns only the sandbox DB),
# so it is structurally incapable of touching prod 'erp' (owned by erp_role);
# - no DROP/CREATE DATABASE, no CREATEDB, no superuser — wipe is
# `DROP OWNED BY erp_sandbox_role CASCADE`, reload is `pg_restore`.
#
# The only prod-capable credential on the platform is the superuser provider in
# factory postgres/iac, exercised solely in the human-gated postgres.yaml CI —
# this script never uses it.
#
# Requires: kubectl (context on the lab cluster), and a postgres:16 image
# reachable by the cluster. Run from anywhere.
#
# Usage:
# ./sandbox-lifecycle.sh refresh-from-prod # iso-prod seed: prod DB -> erp-sandbox
# ./sandbox-lifecycle.sh sync-documents # copy mycompany/ uploads (logo, PDFs)
# ./sandbox-lifecycle.sh refresh # refresh-from-prod + sync-documents
