Add `get_internal_type()` to custom field classes for Django compatibility,
annotate path parameters and operation IDs for background endpoints, and
provide serializer context on the RQ base viewset to clear schema warnings.
Fixes#20365
Introduces a new "facility" field in the bulk edit forms for Site and
Location models. Updates fieldsets and nullable fields to incorporate
the "facility" field.
Closes#20438
Introduces cloning functionality for ObjectPermission objects using the
CloningMixin. Updates the constraints field handling, adds JSONField,
and introduces logic to process initial data for cloned objects.
Fixes#15492
Refactors `CableTypeChoices` by reorganizing cable types into more
specific subcategories. Enhances clarity with distinct groups such as
Copper (Twisted Pair, Twinax, Coaxial) and Fiber (Multi Mode, Single
Mode, Other).
Closes#19865
Remove `FHRPGroupAssignmentForm.__init__` logic that tied group choices
to the interface IP prefix. Add `group_id` to the `q` filter to enable
matching by group ID.

* Fixes#20327: Device queries are now faster when including ConfidContexts
Move .distinct() from main queryset to tag subquery to eliminate
performance bottleneck when querying devices with config contexts.
The .distinct() call on the main device queryset was causing PostgreSQL
to sort all devices before pagination, resulting in 15x slower API
responses for large installations (10k+ devices, 100+ config contexts).
Moving .distinct() to the tag subquery eliminates duplicates at their
source (GenericForeignKey tag relationships) while preserving the fix
for issues #5314 and #5387 without impacting overall query performance.
* Add performance regression test for config context annotation
The test verifies that:
- Main device queries do not use expensive DISTINCT operations
- Tag subqueries properly use DISTINCT to prevent duplicates from issue #5387
This ensures the optimization from issue #20327 (moving .distinct() from maintaining
query to tag subquery) cannot be accidentally reverted while maintaining the
correctness guarantees for issues #5314 and #5387.
* Address PR feedback, clean up new regression test
The new regression test now avoids casting the query to a string and
inspecting the string, which was brittle at best.
The new approach asserts directly against `queryset.distinct` for the
main query and then finds the subquery that we expect to have distinct
set and verifies that is in fact the case.
I also realized that the use of `connection.query_log` was problematic,
in that it didn't seem to return any queries as expected. This meant
that the test was actually not making any assertions since none of the
code inside of the for loop over `device_queries` ever ran.
