* Add failing test for diffing polymorphic model instances.
* Make diffing more robust for polymorphic models:
When working with polymorphic models, where a child model inherits from a
parent model, Django's pre_save signal may send model instances in a way
where the log_update() handler receives an instance of the child as the
`old` model, but an instance of the parent as the `new` model.
This leads to a `FieldDoesNotExist` error when a field that only exists on the
child was modified, and `get_field_value()` attempts look up that field on the
parent.
This change makes diffing polymorphic models more robust by considering this
case in `get_default_value()`. Changes to those child fields won't be tracked
in these cases, but at least `django-auditlog` won't prevent the model from
being saved.
* Add `AUDITLOG_USE_BASE_MANAGER` setting configuration
* Adjust `LogEntry._get_changes_display_for_fk_field` behaviour for setting
* Adjust `log_update` and `log_m2m_changes` in `receivers.py` for setting
* Add `ModelManagerTest.test_use_base_manager_setting`
* Add entry in Usage documentation
* (In passing, fix a formatting issue in `usage.rst`)
The `AUDITLOG_USE_BASE_MANAGER` setting has a default of `False` to maintain
initial backwards compatibility with previous versions.
* Add test runner and improve test with multi databases
* Enhance cross-database compatibility and testing

- Add separate test workflows for SQLite, PostgreSQL, and MySQL
* Add `mysqlclient` deps
* fix minor
- Add mysqlclient deps
- upload coverage step
* Fix coverage upload name conflicts in CI workflow
- Add database type to coverage upload names (SQLite/PostgreSQL/MySQL)
* Add test cases for the `mask_str` function
* Add custom masking function support through mask_callable
* Add test cases for custom masking function
* Update documentation for custom masking function

-AUDITLOG_DEFAULT_MASK_CALLABLE to `AUDITLOG_MASK_CALLABLE`
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Refactor: re-arrange test application
This was triggered by the need to run "python manage.py", which is impossible when serving the whole project in the same directory as is configured in INSTALLED_APPS ("auditlog_tests"). This setup is heavily inspired by other jazzband projects.
* Add check for missing migrations
