Pull request overview

This PR updates the codebase for React 19 compatibility by updating useRef type signatures and forwardRef patterns to align with stricter type requirements in React 19.

• Updated @types/react from v18 to v19.2.7
• Modified all useRef calls that had implicit undefined to explicit T | undefined type annotations with undefined as initial value
• Updated forwardRef type casts in ChannelMessageList and ChannelThreadMessageList components
• Removed unnecessary ReactElement imports and replaced with React.ReactElement with proper generic constraints
