chore: remove with*Context HOC wrappers

[oliverlaz]

🎯 Goal

BREAKING CHANGE: Remove legacy high-order context wrappers (with*Context) from stream-chat-react since the docs and internal usage are hook-based (use*Context).

🛠 Implementation details

• Removed the following exported HOCs from context modules:
  • withChannelActionContext
  • withChannelStateContext
  • withChatContext
  • withComponentContext
  • withMessageContext
  • withTranslationContext
  • withTypingContext
• Kept provider/hook APIs intact (*Provider and use*Context).
• Removed now-unused imports/types tied to HOC implementations (including UnknownType usages in these files).
• Deleted now-unused helper src/context/utils/getDisplayName.ts.

🎨 UI Changes
