Subject: [PATCH] Refactor: OpenWebUI (remove numba pin)  (#18026)

* Open WebUI: stop when the install fails three times

The retry loop fell through to "Installed Open WebUI" after the third
failure, so the service was created without a binary and the URL never
answered (#18020). The last attempt now runs under the error trap, which
shows uv's output.

* Open WebUI: keep the retry inline, no function in the script

* Open WebUI: same retry on the update paths, and drop the numba constraint

The migration and update loops in ct/openwebui.sh fell through to
"Updated" after three failures just like the install did. The numba
constraint from #11874 guarded openai-whisper's old pin; 0.12.x depends
on faster-whisper and never resolves numba.

* formatting
