Automatically clean up soft-deleted records after X days. (#14862)

Closes #14726

### Added
- `trashRetentionDays` field to workspace entity (default: 14 days)  
- Automated trash cleanup using BullMQ jobs  
- Daily cron (00:10 UTC) that enqueues cleanup jobs for all active
workspaces
- Per-workspace limit: 100k records deleted per day  
- Calendar-based retention: records deleted on day X are cleaned up X+14
days later (at midnight UTC boundaries)

### Architecture
- **Cron (WorkspaceTrashCleanupCronJob):** Runs daily, enqueues jobs in
parallel for all workspaces
- **Job (WorkspaceTrashCleanupJob):** Processes individual workspace
cleanup
- **Service (WorkspaceTrashCleanupService):** Discovers tables with
`deletedAt`, deletes old records with quota enforcement
- **Command:** `npx nx run twenty-server:command
cron:workspace:cleanup-trash` to register the cron

### Testing
- Unit tests for service with 100% coverage of public API  
- Tested quota enforcement, error handling, and edge cases
