Subject: [PATCH] CI: accept a lower-case Docker absence message in the
 deadline-health cells

On the Ubuntu 26 runner image the Docker CLI reports a removed container as
"error: no such object: ...". The cells runner matched only "No such
object", so a cell whose database container had already gone (SQLite has
none) halted as cleanup unconfirmed. Run 41338240707 on #925 failed this way
on runner image ubuntu26/20261025.179 while the same job passed on other
images. The match is now case-insensitive; the test's fake Docker can answer
in lower case.
