Subject: [PATCH] [fix](trx-frontend-http): fix TDZ on lastSpectrumData at
 style init

Same root cause as the overviewDrawPending TDZ: setStyle() references
lastSpectrumData at module init time but it was declared far below.
Hoist let lastSpectrumData = null to the top variable block and remove
the now-duplicate declaration.
