fix(litellm): remove the trial alias — run 7 failed the safety gate

Alias-present-with-backend-down is a different and worse state than
alias-removed: it re-arms silently the moment anything is served on
10.250.50.54:8021 again, and the next thing served there inherits a
fleet-reachable name without anyone deciding it should. Flagged by
brokkr-smithy-dev; same writer/reader-contract family as ops-lessons §11.

Commented rather than deleted so restoring is uncommenting, not reconstructing.
Verified: /v1/models returns 33 entries, trial absent, a caller gets a clean
400 'Invalid model name' instead of a connection error to a port that could
re-arm. Disposition of the artifact and the alias is the operator's.
