Polish: daily reward via celebration overlay + premium chat to recipient

- Daily reward now routes through the global CelebrationOverlay: new "daily"
  variant + coins count-up; claiming closes the daily modal and fires
  celebrate({variant:"daily", coins}). Unifies the "you earned X" moment.
- Premium (pro) gold chat is now visible to the OTHER player: ChatMessage gains
  senderPro; server resolves each participant's plan once (SocialService.IsPro)
  and stamps it on ChatMessageDto; ChatScreen styles incoming bubbles with
  .premium-chat when senderPro. Mock marks ~half its friends pro so it's visible
  offline too.

Verified: tsc + next build + dotnet build all pass.
