/**
 * E2E test bootstrap. Runs inside the `bun` test container (see
 * devops/local/docker-compose-test.yaml) against the dockerized stack:
 *
 *   - `prisma migrate reset` so the schema matches HEAD.
 *   - `redis-cli FLUSHALL` clears queues + locks + nonce.
 *   - Fund the operator wallet on the anvil fork with xBZZ + xDAI via
 *     `fundOperatorFromEnv()` (anvil_setBalance + xBZZ whale impersonation).
 *     The contracts themselves already exist on the fork — they're managed
 *     by the t4t repo and live on Gnosis mainnet; the fork inherits them.
 *   - `evm_snapshot` so each spec can revert to a clean fork.
