fix(2meet-data-optimizer): deactivate and uninstall clear every scheduled event and tmdo_* option

- One CRON_HOOKS list for deactivate() and uninstall; wp_unschedule_hook() also
  removes events scheduled with args (tmdo_drift_resync, backfill batches).
- Fix the wrong wpdo_user_stress_test_batch name; add migration tick,
  entity backfill, auto-promote and all stress-test batch hooks.
- Uninstall sweeps tmdo_* options and _transient_(timeout_)tmdo_* rows too.
- Verify: InstallerCleanupTest (3 new), unit 711, integration 611, phpcs 0
- PR: PR-138 (manual F-4, F-5)
