fix(insights): load the intraday pulse chart through the shared chart runtime

The pulse page imported the intraday area chart directly, so its
`from "recharts"` import minted a second recharts fingerprint chunk and
pushed total client JS past its budget. Route it through the shared
chart-runtime barrel via the same single next/dynamic boundary every other
chart uses, so recharts stays one shared chunk.
