Update npm packages for the UI (#432)

Upgraded most packages to current as of 2025-05-09 for almost everything.
Remove the erroneous extra dependency to old xterm package since the correct @xterm/xterm package was already included (suspect a bad merge) and it was causing issues with react 19.1.
Switched to using the hooks exposed in the usehooks-ts package (this package was already referenced, suspect a bad merge) removing our private copies of useInterval, useIsMounted, useResizeObserver which are identical.
Added import of JSX from react now needed because NPX is not in global scope in react 19.x.
Explicitly cast the ref of included elements due to change in react 19.x
