feat(attributes): MATK range min~max no snapshot + display

Espelha breaking change do server (S_ATTRIBUTE_SNAPSHOT_FULL agora envia
matkBaseMin/matkBaseMax em vez de matkBase unico) para suportar MATK
pre-renewal puro (rathena status_base_matk_min/max).

- FZeusAttributesPayload: MatkBaseMin/Max em vez de MatkBase
- FZMMOAttributesSnapshot: idem (BlueprintReadOnly)
- ZMMOStatusWindowWidget: exibe "MATK min ~ max + equip"
