Synthesize a short preview of one of the podcast's voices (returns MP3 audio)

POST 
/v1/public/campaign-offer/:networkId/:campaignId/:token/preview-voice

Public, token-authenticated action that synthesizes a short sample of a selected podcast voice so the recipient can hear it before accepting. Requires prior code verification, otherwise returns 409. Keyless callers are rate limited per token and per client IP (429 on excess); a valid API key for the campaign's network bypasses the limit. Synthesis runs against an upstream voice provider, which may return 502 on failure.
