Fix TypeScript import error for React in RSC files

Changed from:
  import React, { createContext } from 'react'

To:
  import * as React from 'react'
  import { createContext } from 'react'

This fixes the CI error:
  error TS1259: Module can only be default-imported using the 'esModuleInterop' flag

The @types/react package uses 'export =' syntax, which requires namespace imports
unless esModuleInterop is enabled. Using separate imports avoids this requirement.
