List TikTok ads

Lists individual ads with their on/off state, delivery status, the video and cover images behind each one, the ad text and call to action, the destination URL and — most usefully — TikTok's review verdict, read from the ad's delivery status. Use when: you need ad ids, the user asks what creative is live, or an ad is not delivering and review might be why. Do not use it to judge creative quality: get the numbers from tiktok_get_ad_performance first, then look at the copy. Do not invent a rejection reason: TikTok's API says an ad was not approved but never why, so ask the user to read the reason next to the ad in Ads Manager. Returns video_id for each ad, which is what tiktok_add_ad needs to reuse a creative that already works, and tiktok_list_ad_videos can turn into the video's dimensions and duration. Pass adgroup_id or campaign_id to scope the list; without either you get every ad in the advertiser account.
