Subject: [PATCH] fix(atlas): add full eligibility checks to delayed retry
 callback

Address Cubic P1 review: timer callback now re-checks failure backoff
count, boulder session membership, and running background tasks before
injecting continuation, matching the main idle handler's eligibility
gate.
