The settings collection was a single global document, so every org
shared one SMTP config, alert config, retention policy and ESO read
token. GetSecretGroupDecryptedAny then flattened every org's secrets
for a group into one map, meaning any tenant's token read every
tenant's secrets.
- settings gains org_id; GetSettings/SaveSettings/RotateSecretsReadToken/
GetWorkflowLogRetentionDays all take orgID
- VerifySecretsReadToken replaced by ResolveSecretsReadToken, which
resolves the org from the presented token's hash; the ESO endpoint
derives its org from the token rather than a session, since it is
called machine-to-machine
- GetSecretGroupDecryptedAny deleted in favour of the org-scoped variant
- settings and token-rotation routes now require owner/admin
- offline sweep and log retention resolve org per server / per run
- migration 0002 stamps the legacy settings doc with the default org
Note: /api/settings now 403s for members; the web settings page needs a
matching role check.
