Leaving the context-length prompt blank in the custom-endpoint wizard said
"will auto-detect" and then went silent, so users could not tell whether their
endpoint runs on a detected window or the runtime's default fallback (which
shapes compression and prompt-cache behaviour). After the save prompt, run the
same resolver the runtime uses (with the endpoint's URL and key) and print
either "auto-detected N tokens" or "not detected — using the default N tokens".
Feedback only: the probe result is not persisted, and a failing probe never
blocks the save.
Fixes#2513. Approach from PR #2522 (@ygd58) and PR #85499 (@Luna161), both
written against the pre-decomposition wizard module.
