+ * Remove accidentally set BTC liquidity limit.
+ *
+ * On 2026-01-19 at 16:09 UTC, the limit field on the BTC liquidity_management_rule
+ * was accidentally set to 0.8863205, causing BuyFiat transactions over ~0.78 BTC
+ * to fail with LIQUIDITY_LIMIT_EXCEEDED (e.g., transaction 296735).
+ *
+ * This migration sets the limit back to NULL (no limit) for BTC.
