/**
 * Ads Phase R5.1 — 6-step campaign wizard UI.
 *
 * R5 added the tenant-scoped FormRequest fields (ad_platform_uids[],
 * ad_creative_uid, ad_audience_uid).  R5.1 surfaces them as wizard steps
 * and wires the service to persist them.
 *
 * Verifies:
 *   1. Migration applied — ad_audience_id column on ad_campaigns.
 *   2. AdCampaign casts + relations include ad_audience_id + audience().
 *   3. AdCampaignController::create passes platforms + creatives +
 *      audiences (tenant-scoped, active platforms only).
 *   4. AdCampaignService::create resolves ad_creative_uid → ad_creative_id.
 *   5. AdCampaignService::create resolves ad_audience_uid → ad_audience_id.
 *   6. AdCampaignService::create attaches ad_platform_uids[] via the
 *      belongsToMany pivot, scoped to current customer + active status.
 *   7. AdCampaignService::create with empty/missing wizard fields keeps
 *      the legacy create flow working (backward compat).
 *   8. Wizard view markup carries all 6 steps + R5.1 lang keys.
