Split out of #68919 per review. Edge-case fixes in the deadline model and serialization paths:
__class_pathahead ofreference_type(custom references can share a builtin's class name), and a reference with no importable__class_pathraises a clear error instead of aKeyError.__repr__onDeadlineandDeadlineAlertnever raises (guards thedagrunrelationship post-cascade-delete and the dict-shaped interval).prune_deadlinesexcludes missed deadlines so a missed deadline's queued callback is not cascade-deleted.
