fix(tests): remove curl-based healthcheck from sqld container

The ghcr.io/tursodatabase/libsql-server:latest image is based on
debian:bullseye-slim and does not include curl. The health check was
always failing, causing the container to be reported as unhealthy and
blocking the api service from starting.

Instead, use service_started condition since sqld starts nearly
instantly and the workflow already has an explicit health polling step
that checks sqld readiness from the host before running tests.
