fix(usage): only auto-poll Copilot/ChatGPT quota for current provider

CopilotQuotaFooter and CodexOauthQuotaFooter called their hooks with a
hardcoded `enabled: true` plus an unconditional 5-minute refetch and
refetchOnWindowFocus, so non-current reverse-proxy cards kept polling
in violation of the project's "only the active provider auto-queries
on cooldown" rule. With multiple Copilot or ChatGPT accounts bound to
different cards, every card kept hitting its own usage endpoint.

Adopt the same pattern as useUsageQuery: keep `enabled` independent of
isCurrent so first-fetch and manual refresh still work, but gate
refetchInterval / refetchIntervalInBackground / refetchOnWindowFocus on
a new `autoQuery` option, and thread `isCurrent` from ProviderCard
through the footers into the hooks.
