feat: add unified upload telemetry

Move upload activity out of the global footer into a compact eight-row sidebar panel, add vertical metric transitions, and draw a smoothed green upload-speed sparkline in the header. Localize the new surfaces, cover responsive Electron behavior, and extend the strict public source allowlist for the new bounded speed-history module and its tests.
