Schedule a budget increase

Pre-schedule a temporary budget increase (Black Friday, a launch, a sale) instead of editing the budget by hand on the day. Same target rule as the GET: exactly one of `campaignId` / `adSetId`. Two Meta constraints worth knowing before you call it. `timeStart` / `timeEnd` must fall on a 15-minute boundary, and a campaign cannot mix `ABSOLUTE` and `MULTIPLIER` across its schedules — the second type is rejected with "Can't mix your budget scaling selection". Window rules (must sit inside the campaign's run dates, minimum lead time, no overlap) are Meta's and its message is forwarded verbatim.

List DSA beneficiary/payor suggestions

Returns Meta's suggested beneficiary/payor names for an ad account, derived by Meta from the account's recent activity. Useful for prefilling `dsaBeneficiary`/`dsaPayor` inputs, or the defaults sent to `PATCH /v1/ads/accounts`, in your own UI. Meta returns a single flat list. Entries are not labeled as beneficiary or payor, and since these are legal disclosures Zernio never applies them automatically: let your user pick the right entity. The list may be empty for accounts with little activity. Meta accounts only.
