fix: start nginx LAST so startup logs appear in HF SSE

HF's runtime SSE only captures container output during STARTING state
(before port 7860 responds). Move nginx from first to last service so
all boot info + service status appears in the SSE stream. Also:
- Rename /logs → /api/logs (HF intercepts /logs path)
- Revert to bash entrypoint (Python wrapper didn't help)
