Probing the live `/refund` endpoint confirmed: float `12.50` \u2192 totals stay `0.0`; string `\"12.50\"` \u2192 reconciles to `12.5`.\n- Implemented `submit_refunds` to POST records to `/refund` (mirroring `client.submit_batch`), serializing amounts as string decimals (`str(r[\"amount\"])`) so refund totals reconcile server-side.\n\nI did **not** touch the tests or `client.py`. Worth noting: `client.py::submit_batch` still sends raw floats, so `tests/test_billing.py` is likely failing for the same reason \u2014 but that's outside this task's scope.
