ruff: drop stale SLF001 noqa, wrap json.load in a context manager (SIM115), remove unused imports + placeholder-less f-strings; ignore PLR0912/PLR0915 for one-off scripts.

Migration 18: ops.contract_check_log table — append-only log of probes
against the Tracksolid Pro endpoints we depend on.
New worker app/workers/contract_check.py — per run:
- jimi.oauth.token.get (token refresh succeeds)
- jimi.user.device.location.list per configured target (parse first item
with JimiPollFix)
- jimi.device.location.get with a sample IMEI from the list (parse first
item with JimiPollFix)
Each probe logs success or {error_class, error_detail, sample}; failures
are recorded, not raised.
slo_metrics now also computes contract_drift_days = days since the most-
recent successful probe of the laggard endpoint. With threshold 1d (from
mig 5), a single failed daily run flips the badge red within 24h.
cron entrypoint registers the check daily at 02:00 UTC plus once on
startup, gated on TRACKSOLID_APP_KEY + a configured target.
