Offload build output functions: (#11990)

* Offload build output functions:

- cancel output
- scrap output
- complete output

Perform these in the background worker, and monitor for progress on the frontend.

* Refactor "build cancel"

- Offload expensive ops to background worker

* Offload build complete task

* Remove @atomic decorator from functions

- Allows operations to be performed "incrementally"
- If one task times out, the next task will get the rest

* Bug fix

* Bump API version

* Fix isInTestMode check

* Handle case where task returns immediately

* Fix docstring

* fix test_api

* Tweak order of operations

* additional unit testing for further coverage

* Adjust unit tests

* Offload order completion tasks

* Remove bad code

* Updated playwright test

* Robustify playwright tests

* Bump number of allowed queries

* Revert "Remove bad code"

This reverts commit 3a3ac3bdc7.

* Revert "Offload order completion tasks"

This reverts commit 6066dabe43.
