## Summary by CodeRabbit

* **Bug Fixes**
* Stop sending notifications to disabled users; skip member invites when
workspace names contain URLs/domains
* Improve mail retry handling (per-recipient exhaustion, expiry, and
cache cleanup)
  * Make many email headers/lead lines more generic and consistent
  * Fail-safe workspace content parsing to avoid crashes

* **New Features**
* 24-hour signup protection for sharing, invites, and invite-link
creation
  * Job-queue: remove jobs by payload predicate

* **Tests**
* Expanded tests for mail jobs, SMTP hostname handling, payment
checkout, job-queue removal, and abuse-detection utilities
  * Updated test fixtures to set createdAt timestamps for new users

* **Chores**
  * Added required name input for test-email mutation
  * Database flush retry with deadlock detection/backoff
