v3.4.156

Fixes

• Backfill jobs no longer permanently fail when the linked Google account is disconnected. Previously, if a product's backfill job ran while its Google account was disconnected (expired token, brief outage), it was marked failed outright with no way to recover — the job could only be resumed by adding new Drive resources, not just reconnecting the account. It now retries via the existing attempts/stale-reclaim mechanism, since a disconnected account is usually transient.
• Access-revoked emails now also notify the order's billing email when it differs from the Drive recipient (e.g. gift orders), matching the fallback already used for access-granted emails.
