The budget's funds history: who moved its funds in or out, how much, from or to where
and why. Newest first (created_at desc, then id desc). Closed budgets still return
their history.

Access

• Admin / budgets_manage users and Cardda staff.
• Members of the budget: its manager ("Encargado"), a co-manager or a participant,
  explicit or by holding one of its non-canceled cards.

Someone who sees the budget only because it's open to the company
(access: company) gets 401. A budget outside the caller's scope returns
404 Not Found.

Pagination

_start/_end paginate (25 rows by default), with Content-Range and
X-Total-Count in the response. There is no _field/_order sorting.

What it holds

The history starts when this endpoint was released; older movements are not
backfilled. Assigning or unassigning loaded prepaid cards, period renewals and the
budget's creation are not recorded, so the rows don't add up to
allocated_amount_cents.
