Description

Moves the UnitEnum instanceof check before JsonSerializable and method_exists($data, 'toArray') in Entity::normalizeValue(), so that enums implementing toArray() are always normalized as enums rather than as generic objects.

Fixes #10136

• fix test: correct toRawArray() assertion for injected enum

toRawArray() returns raw $this->attributes, so an injected enum object stays as an enum object — not the backing string value. The real regression is that hasChanged() must return false (normalizeValue() handles UnitEnum before toArray()).
