[CLNP-8533] fix: detect super group channel via premiumFeatureList

[sf-tyler-jeong]

The server is phasing out the allow_super_group_channel flag in application_attributes. Update isSuperGroupChannelEnabled to read super_group_channel from appInfo.premiumFeatureList, consistent with how delivery_receipt is already detected.

isBroadcastChannelEnabled is intentionally left on application_attributes.allow_broadcast_channel: per the server team it is not exposed through premiumFeatureList and stays ACL-gated.

Add a shared SUPER_GROUP_CHANNEL constant in utils/consts.ts and unit tests covering both helpers.

Note: release only after the server change ships to all regions, otherwise apps that enabled super group via ACL only would lose the channel type until then.

lgtm~
core-ts 쪽에서는 관련된 내용이 없나요?

core-ts(@sendbird/uikit-tools)에는 관련 상수 정의만 있고, 실제로 그 값을 읽어 super group 활성화 여부를 판단하는 로직은 존재하지 않습니다. 감사합니다~!!

참고로 상수는 2개 정의되어 있습니다.

• constants/applicationAttributes.ts → allow_super_group_channel: 'allow_super_group_channel'
• constants/premiumFeatures.ts → super_group_channel: 'super_group_channel'

allow_super_group_channel 가 필요 없다면, core-ts에서도 빠져 있는게 좋을거 같습니다.

core-ts repo에서 수정하고 PR 리뷰 요청 드렸습니다. 감사합니다.
