Find ChatGPT Ads location ids

Turns a place name into the location ids the platform targets by. "Berlin", "California", "Japan" go in; ids, canonical names and location types come out. Use when: the user names any place the ad should run in, always before chatgpt_launch_ad. The launch tool accepts ids only and refuses anything that looks like a name. Do not guess an id, reuse one from another ad platform, or pass a place name straight into a write — a wrong id spends real money in the wrong country and the platform will not warn you. Returns every match with its type and country code, so you can tell one Springfield from another. Types include country, region, city and dma (a US media market covering several cities, which is often what a metro name resolves to). If several matches look plausible, show them and ask the user which one they mean rather than taking the first. A match only proves the place exists. It does not mean this ad account can advertise there: ask the user to confirm the market is enabled for their account before launching in it. Costs nothing, so resolve every place the user mentions, one place per call.
