[web] enable mongo notablescan in CI (#29501)

* [monorepo] record ERROR/FATAL log messages in junit report

* [web] put SaaS specific code behind feature flag

* [web] use split test cache for getting user assignments

The unit tests needed updating as they did not replicate any of the
 mongo filtering. The acceptance tests cover this logic.

* [web] make better use of existing indexes

* [web] avoid col-scan in tests of notifications module

* [web] remove cleanup of empty feedbacks collection

* [web] add assertion for reason of rejected request in launchpad test

* [web] add missing indexes

* [web] enable mongo notablescan

* [web] make emailNotifications tests compatible with notablescan
