DRF's RelatedField asserts queryset is not None (unless read_only) at
__init__ time, i.e. when the class body of the Serializer is
evaluated - not when the field is later used. The previous code passed
queryset=None and tried to patch it in the serializer's own __init__,
which never ran in time because construction of the field itself
already raised. Pass the real querysets directly at class-body level
instead, matching the standard DRF/NetBox pattern; the deferred
per-instance model imports are no longer needed since serializers are
only imported once all apps are ready anyway.

Introduces a NetBox 4.6 plugin for planning rack layouts (RackConcept,
ConceptDevice) without creating real dcim.Rack/dcim.Device objects, so
blueprints never appear in rack/device lists, utilization reports, or
IPAM.
Features:
- Copy paths: real rack -> concept, concept -> concept (clone), and
concept -> one or more real racks (deploy, with name patterning and
dry-run support)
- Manual concept creation via a dedicated "Rack Concepts" nav menu
- Tenant and tenant group assignment on concepts and planned devices
- Partial-width device placement (1/1-1/4) with slot-based collision
detection, matching netbox_utilities' partial-width feature
- Custom drag-and-drop elevation (netbox-reorder-rack operates on real
Device querysets, which concepts don't have) with server-side
validation of every move
- Full REST API, filtering, CSV import, bulk edit, search integration
- Optional, config-driven interop with netbox_utilities (partial-width
field mapping) and netbox-reorder-rack, degrading gracefully when
either plugin is absent
