Add regression tests for tenant provisioner system-settings seeding

Table of Contents

This page is a capture in the next bucket of the product backlog — a pre-sprint idea, not yet pulled into a sprint as a story.

What

Add a pgTAP (or equivalent) test that provisions a tenant via iam_tenant_provisioner_create.sql and asserts every current system.%-prefixed setting from the system tenant (except system.bootstrap_mode) lands on the new tenant with the same value, plus a direct test of ores_variability_seed_tenant_system_settings_fn in isolation (covering the party-scoping filter added in PR #1496 review).

Why

There is currently no automated coverage for tenant provisioning at all in projects/ores.sql/test/, and this is precisely the bug class being fixed here — a setting silently missing per-tenant. A regression test would catch a future accidental exclusion automatically instead of relying on manual "verified live" checks each time.
