  • The deadline alerts endpoint fetches the latest serialized Dag by
    ordering all rows for a dag_id descending and reading the first one.
    Without a LIMIT, the database materializes every serialized version of
    the Dag when only the newest is needed. Cap the lookup at a single row.

  • Sort imports in deadline alerts UI route tests

  • UI: Allow reading deadline alerts of a specific Dag version

A backfill run executes the Dag version that was current when it was
queued, whose deadline alerts may differ from the ones deployed today.
The endpoint could only ever resolve the newest serialized Dag, so the
UI reported present-day alerts for historical runs and misrepresented
what those runs were actually held to.

Resolving the version through DagVersion.version_number also removes a
reliance on the serialized_dag primary key sorting chronologically,
which only held because uuid7 happens to be time-ordered and would give
the wrong row if an older version were serialized after a newer one.
Only the primary key is read, so the serialized Dag blob no longer
crosses the wire for a lookup that discards it.
(cherry picked from commit 1b3121d)
