fix(docker): make wait-for-api.sh POSIX and enforce LF line endings (#586) (#598)
* 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).
