[Creators] Update to Roulette Result Delivery

Roulette result delivery has been updated. 

Fans will no longer receive roulette results via chat (DM), and can instead check them on the Roulette Sales History page.
This allows both creators and fans to use the chat more comfortably.

📌 What’s changed?

ℹ️ Update details

- Roulette results are no longer sent via chat (DM).
- Fans can check their roulette participation history 
  on the [Roulette Sales History] page.
- Only rewards that require follow-up 
  (physical, custom, collection completion) will be sent via DM.

📌 How can I check fans’ roulette history?

1. Roulette Play page > Winning History 

• Tap ‘Winning History’ at the bottom right of the Roulette Play page.
• You can view all winning records for that roulette.

2. Chat with the fan > Roulette Sales History 

• Tap the top-right menu in the chat > [Roulette Sales History].
• You can view all participation records for that fan in your roulette.

📌 Rewards that still send DMs 

Only rewards that require follow-up will be sent via chat (DM) as before: 

• Physical rewards — Shipping address input, etc.
• Custom rewards — Rewards requiring communication between creator and fan
• Collection completion rewards — When a fan collects all rewards

💬 With a cleaner chat, you can focus more on communicating with your fans!
