+- Fix: wire AgentRouter's existing console balance fetcher into the Dashboard Quota UI (visibility gate + provider-limits data path + background sync) so its wallet balance renders instead of falling back to "Usage API not implemented" (#10078)
+- Fix: AgentRouter's dollar balance now renders as a currency-formatted "$X.XX" credits row in the Dashboard Quota UI instead of a bare percentage, and an exhausted wallet always shows exactly $0.00 (#10078)

+/**
+ * usage/agentrouter.ts — AgentRouter (New-API) balance quota shapes the Provider
+ * Limits dashboard expects.
+ *
+ * Reuses the already-registered preflight/monitor fetcher (OpenAI-style routing
+ * apiKey vs console System Access Token + New-Api-User id) instead of re-implementing
+ * the HTTP call, so the 60s in-memory cache in agentrouterQuotaFetcher.ts is shared.
+ *
+ * AgentRouter exposes a raw New-API credit balance, not a real grant to divide by —
+ * so, following the DeepSeek boolean-availability precedent, `remainingPercentage` is
+ * only a two-state signal (100 = has balance, 0 = exhausted) used for the quota-card
+ * bar color. The human-meaningful number — the actual USD balance (rawQuota /
+ * QUOTA_PER_UNIT) — MUST travel inside `quotas.balance.remaining` so the Dashboard
+ * Quota UI's credits-row renderer (quotaParsing.ts::parseAgentrouterQuota, which reads
+ * `quota.remaining`/`quota.currency`) can format it with a currency symbol instead of
+ * dropping it: `getUsageForProvider()`'s top-level `remainingUsd`/`availableUsd`/
+ * `balance` sibling fields exist for API/CLI consumers only — parseQuotaData() (the
+ * Dashboard renderer) never reads them, only `data.quotas` (#10078 follow-up).
