* Chore: Speed up test setup by hashing passwords with MD5 and batching index writes
Don't use Django's default PBKDF2, about 600 ms per use and 110 uses across the suite. Switches to MD5 instead.
Also fixes a test that didn't batch update the search index
* Chore: Stop the invalid webhook params test from waiting on a Celery broker
test_workflow_webhook_action_url_invalid_params_headers left send_webhook.apply_async unpatched, so it tried to actually enqueu and waited for the timeout.
The model factories lived in the documents test package, but three other
apps needed them. The AI, mail and testing suites all reached across an app
boundary to import from documents.tests.factories, which made a private test
package into a shared dependency.
The factories now live in the shared testing package, where cross-app use is
the intended use.
* docs(search): document the query grammar paperless actually supports
* docs(search): cover ?/bracket wildcards and the no-stemmer fallback
* Shorten things up, use tables and less wordy stuff. Fixes some test doc strings that referred to the documentation
* Silly sonarr
* Feature: parse advanced search with whoosh-compat and delete the hand-written translator
* Don't cover these, they exist for defensive, but there's no other current diagnostic
* A mix of more no cover and tests
* Route SCHEMA_FIELD_MISSING into an error, not an HTTP 400
