Remove name from usage limits (#54481)

Removes the optional `name` field from usage limit configs, which was never editable in the UI (always `None` on create, only echoed back). It's dropped end to end: the backend model/serialization, the HTTP request/response types plus their OpenAPI spec and generated TS client, and the dashboard config type. This is safe for persisted data, reads of older `_usage_limits` documents and audit-log configs ignore the leftover `name` key (the Convex deserializer skips unknown fields).
