Keep credit-backed accounts usable and show live credits in the dashboard

[mws-weekend-projects]

• This keeps accounts selectable when weekly quota is exhausted but credits are still available.
• It also shows the live credit balance in the dashboard and handles unassigned request log rows.

Make apiKeyName optional in request log schema

RequestLogSchema now requires an apiKeyName property (z.string().nullable()), but the current backend request-log contract does not emit that field (see RequestLogEntry/to_request_log_entry), so parsing /api/request-logs responses will fail whenever rows omit apiKeyName, breaking the request log view despite otherwise valid data. Use .optional() (or add server-side emission) to keep the client compatible.

Useful? React with 👍 / 👎.

Maintainer cleanup: closing this as stale / no longer merge-ready against the current main.

This PR has been open across substantial main-branch churn and is currently carrying at least one stale signal (conflicts/blocked or failing checks, outstanding codex: needs work, draft/old branch state, or overlap with newer/current implementation). Keeping it open is making the PR queue harder to reason about.

If the change is still needed, please open a fresh, focused PR rebased on current main with green CI and a clean Codex review.

Revived on a maintainer-owned branch as #767 because this PR head has maintainerCanModify=false and cannot be updated here. Keeping credit to the original implementation in the replacement PR.
