CHW-5601 SettingsPersistFailed

failed to persist settings; retry shortly and check operator logs if the failure repeats

Default message: failed to persist settings; retry shortly and check operator logs if the failure repeats
HTTP status: 500 (server)

Problem. A settings write reached the store but failed. Cause. A constraint violation, IO error, or transaction failure inside the configuration store. The fields.field value identifies which setting was being written. Fix. Retry shortly; if the failure persists inspect operator logs for the underlying error. HTTP 500.

Policy store unavailable reuses CHW-5301 PolicyStoreUnavailable — the configuration policy handlers reference that code directly. See that page for the full description.
