WHY IT NEEDS A POLICY

Why create_meta_campaign needs a policy

This tool creates a new ad campaign on Meta platforms. While it starts in PAUSED state (so no immediate spend), it provisions a campaign with budget, targeting, and creative assets. It's reversible (there's a delete_meta_campaign sibling), so it falls under Write rather than Destructive or Financial.

From the tool's definition Create a complete Meta (Facebook/Instagram) ad campaign in one call — campaign + ad set with targeting + creative + ad. Created in PAUSED state.
