The health ledger records failures per account and provider, and since
background work leaves out a benched provider, an operator who fixed the
instance-wide provider in the admin AI settings still saw every account's
background work sit out the pause the broken setup had earned, up to a day.
Only a person's own provider settings and the Codex sign-ins forgot the
record.
A successful save of the admin AI settings now forgets what the ledger
recorded for admin-openai on every account and closes the status notes'
negative windows, the same reset a person's own save makes for theirs
(clearStatusNegativeWindows without an account covers every record). The
ledger comments that still said a benched row only deprioritises now say
what it does for background work.
