The weekly summary email task crashes for a user who has no accessible lab: ValueError: You do not have access to lab selection : None. 237 occurrences across shariant prod / demo / test / security — recurring weekly.

The per-user send path should skip (or gracefully handle) users with no lab rather than raising.
