"""Disable RLS on all system/auth/config/plugin tables for crm_api startup.
This migration disables RLS on all tables that are accessed during
startup, login, or plugin activation — before a tenant context is set.
RLS remains active only on business-data tables (contacts, addresses,
attachments, etc.) where tenant context is always set before access.
Revision ID: 0081
Revises: 0080
