List LinkedIn campaigns (ad sets)

Lists campaigns (ad sets in Campaign Manager) with their group, status, objective, format, bid, daily and total budget, schedule, audience-expansion settings and a one-line targeting summary. Use when: the user asks what is running, before any change to a campaign (you need its real current settings, not a remembered one), and to get the campaign ids every other LinkedIn tool takes. Do not use it for spend or results — it returns configuration only. Performance comes from linkedin_get_campaign_performance. Do not assume a campaign with status ACTIVE is delivering: check the serving issues column, which is where LinkedIn reports an exhausted group budget or a creative still in review. Returns one row per campaign. Money is a decimal in the account currency. If nothing comes back, check the status filter before telling the user the account is empty — DRAFT campaigns are excluded from an ACTIVE filter.
