paperless-ai's Settings validation hard-codes a gpt-4o-mini probe
(independent of OPENAI_MODEL); the bare alias was removed in the
2026-05-29 prefix-taxonomy refactor, so the probe 400s and blocks
saving settings. Re-add a single narrowly-scoped shadow alias routed to
free local llama3.1:8b (the one probe name unreachable via a prefix).
Trade-off note updated so this isn't read as a regression.
