/**
* tests/unit/xiaomi-mimo-selftrack-usage.test.ts
*
* Xiaomi MiMo exposes plan usage only behind a console session cookie (the API
* key cannot reach the upstream usage endpoint), so OmniRoute SELF-TRACKS it:
* it sums the tokens it routed to the connection in the current UTC month
* (usage_history) and compares them to the known Token Plan monthly limit
* (4.1B). These tests cover the aggregation helper + the fetcher shape, with a
* real temp DB.
