Create a paused Meta image campaign

Builds a complete single-image campaign: campaign, one ad set, the image upload, the creative and one ad. The campaign is created PAUSED and its ad set and ad ACTIVE inside it, so nothing spends until the campaign is turned on, and turning it on launches the ad. Say that the campaign is paused when you report the result, with the two links the result gives (Ads Manager and the campaign's page in Adako), and offer "enable all": one meta_resume_entity call on the campaign, listed in the result as go_live.enable_all, one approval. Use when: the user has agreed on objective, budget, audience, image and copy. Gather those first — resolve locations and interests with meta_search_targeting, the Page with meta_list_pages, the pixel with meta_list_pixels, and check the image with meta_validate_creative_url. Do not use to add another ad or audience to something that already exists; this always creates a new campaign, and calling it twice for the same brief creates two campaigns that both spend. Do not pass free text for locations or interests — only ids from the resolver tools are accepted. Returns the four new ids and reads the statuses back so you can confirm the campaign is paused (the ad set and ad read ACTIVE, held by the campaign). Refuses to start when: the account has no promotable Page; the account has several Pages and none was chosen; a sales or leads objective has no pixel; a country code is not ISO or a region or city key is unknown to Meta; the targeting reaches the EU/EEA without dsa_beneficiary and dsa_payor; a date is in the past or a timestamp has no UTC offset; the budget is below Meta's minimum for this account; the objective is app promotion or the goal is an instant form; a special ad category is combined with targeting Meta forbids for it; or image_url does not answer with a JPEG, PNG or GIF file under 30 MB. Ask the user for the missing piece rather than substituting a value.
