React Upgrade to Latest - 18.3/19 RC #618

Description

Currently Ramp doesn't support React 18.x, and fails to compile due to unsupported asynchronous implementation of useEffect hook in React. As React is upto 18.3 (latest) we need to add support for it.

Done Looks Like

• Investigate effort to upgrade to React 18.3 and then again to React 19
• Upgrade to React 18.3 and get code stable again
• Change unsupported code: asynchronous React.useEffect()
• All dependencies work with the upgrade
• Attempt upgrade to React 19 RC (moved to a separate issue: React 19 Upgrade #638)
