* fix(docker): make wait-for-api.sh POSIX and enforce LF line endings (#586)
* fix: restore inline comment on final exit 0
Addresses review feedback: the comment on the final `exit 0` explains
a non-obvious design decision (frontend still starts when the API
never became ready, so users get a usable UI with connection errors
rather than a dead container).

Users reported "Unable to Connect to API Server" errors on startup
because the frontend started before the API finished initialization
(database migrations, etc.).
- Add wait-for-api.sh script that polls /health endpoint
- Update supervisord configs to use wait script instead of sleep 5
- Waits up to 5 minutes for API to be ready before starting frontend
- Applies to both single-container and multi-container deployments
Fixes#315
