WHY IT NEEDS A POLICY

Why upload_voice_audio needs a policy

Uploading audio files creates new resources (audio assets) in the LigueLead system that can be used in voice campaigns. This is a Write operation (create/store), not Read (no query or retrieval), not Execute (does not run arbitrary code or trigger campaigns itself - it only stages content), and not Destructive (data is not deleted/overwritten).

From the tool's definition Tool description states 'Upload an audio file for voice campaigns' - this is a create operation that stores new data in the system. The context of bulk communication workflows and campaign management indicates this modifies campaign assets.
