chore(test): add missing docker=True to TestFileTransferLimitsEnterprise fixture

The TestFileTransferLimitsEnterprise fixture was missing docker=True and
ignore_existing=True in the prepare_env_for_connect() call. This was
dropped in b5a8c23 (QA-1527) when migrating file transfer
tests to the mender docker client.

Without these flags, prepare_env_for_connect spawns a non-docker client
in a docker-client environment, causing every file transfer limits test
in the Enterprise class to time out with HTTP 408 instead of receiving
the expected 403 from the device.

The fix aligns the Limits Enterprise fixture with the Download Enterprise
fixture, which already passes docker=True, ignore_existing=True.
