DeepSeek quota probe hardcodes USD symbol: CNY balance shown as \$76.88 instead of ¥76.88 #5692

Summary

The DeepSeek quota probe reports the account balance with a hardcoded $ prefix, regardless of the currency returned by the DeepSeek API. A CNY-denominated account with a balance of 76.88 CNY is displayed in the dashboard as "API balance ($76.88)", which misrepresents the currency. I expected the label to use the currency reported in balance_infos[].currency (e.g. "API balance (¥76.88)" for CNY).

The affected code is fetchDeepSeekQuota in src/providers/quota/vendor-probes-key.ts: the probe reads total_balance / granted_balance from balance_infos rows and prefers a USD row, but the label construction hardcodes $ for whichever row is selected. When the account only has a CNY row (the common case for DeepSeek accounts billed in CNY), the label is wrong.

Suggested fix: derive the symbol from the selected row's currency field (CNY → ¥, USD → $, otherwise show the currency code) instead of hardcoding $.

Reproduction

1. Configure a DeepSeek provider (baseUrl: https://api.deepseek.com) with an API key from a CNY-billed account.
2. Open the dashboard → Providers → DeepSeek → refresh quota (or call GET /api/providers/keys?name=deepseek&quota=1&refresh=1).
3. Observe the quota label: API balance ($76.88).
4. Call GET https://api.deepseek.com/user/balance with the same key: the payload reports "currency": "CNY" inside balance_infos, i.e. the amount is 76.88 CNY, not USD.
