DeepSeek API balance pill for the DSH Web GUI: shows remaining credit in the left sidebar footer with low-balance alerts, spend history, and a one-click top-up link. The API key never leaves the host process — the host half resolves it through the dsh credentials service and queries api.deepseek.com/user/balance; the browser half only fetches redacted balance JSON from a loopback route.
