Add a Manager proxy role.
Vincent Pelletier authored
This fixes cases where a user accesses a bank account of another agency
(this can happen for operation imports at country scale).

It is safe to set a Manager proxy role on this script as it is called on
the only accessed document, so security checks were already done (or
bypassed) upon fetching our context.
