fix(acl): use camelCase indicatieGebruiksrecht so OpenZaak honours it (refs #103)

The ZGW Documenten API property is indicatieGebruiksrecht (camelCase); the
all-lowercase key was silently dropped on write (DRF camel-case mapping),
leaving the field null so the zaak still could not close. Correct the JSON
name on the DTO and both assertions to match the ZGW spec.
