## Routes: `direction` replaces `from`, and creation is idempotent

* A route now returns **`direction`** (`mint-fiat`, `mint-stablecoin`, `redeem-fiat`, `redeem-stablecoin`) instead of echoing `from`, and `GET /v0/routes` takes a `direction` filter.
* The `stablecoin` wildcard source currency is gone. Mint-from-stablecoin routes name the currency directly (today, `usdc`).
* `POST /v0/routes` is idempotent. A repeat call with the same inputs returns `200` with the existing route instead of `409 route_already_exists`, which is now reserved for a route id occupied by a row the call couldn't read back. See [200, 201, or 409](/api/endpoints/routes/create#200-201-or-409).
