chore(ruff): Enable I (isort) and stabilize import ordering

- Adopt Ruff `I` (isort) rules for consistent import sorting
- Update intra-app imports to use relative imports within each Django
  app to avoid circular import issues
- Add two `# isort: split` boundaries to keep required imports pinned
  in `__init__.py` modules

 ## Pagination
 
-Queries can be paginated by specifying pagination in the query and supplying an offset and optionaly a limit in the query.  If no limit is given, a default of 100 is used.  Queries are not paginated unless requested in the query. An example paginated query is shown below:
+The GraphQL API supports two types of pagination. Offset-based pagination operates using an offset relative to the first record in a set, specified by the `offset` parameter. For example, the response to a request specifying an offset of 100 will contain the 101st and later matching records. Offset-based pagination feels very natural, but its performance can suffer when dealing with large data sets due to the overhead involved in calculating the relative offset.
+
+The alternative approach is cursor-based pagination, which operates using absolute (rather than relative) primary key values. (These are the numeric IDs assigned to each object in the database.) When using cursor-based pagination, the response will contain records with a primary key greater than or equal to the specified start value, up to the maximum number of results. This strategy requires keeping track of the last seen primary key from each response when paginating through data, but is extremely performant. The cursor is specified by passing the starting object ID via the `start` parameter.
+
+To ensure consistent ordering, objects will always be ordered by their primary keys when cursor-based pagination is used.
+
+!!! note "Cursor-based pagination was introduced in NetBox v4.5.2."
+
+Both pagination strategies support passing an optional `limit` parameter. In both approaches, this specifies the maximum number of objects to include in the response. If no limit is specified, a default value of 100 is used.
+
+### Offset Pagination
+
+The first page will have an `offset` of zero, or the `offset` parameter will be omitted:
 
 ```
 query {
-  device_list(pagination: { offset: 0, limit: 20 }) {
+  device_list(pagination: {offset: 0, limit: 20}) {
     id
   }
 }
 ```
 
+The second page will have an offset equal to the size of the first page. If the number of records is less than the specified limit, there are no more records to process. For example, if a request specifies a `limit` of 20 but returns only 13 records, we can conclude that this is the final page of records.
+
+```
+query {
+  device_list(pagination: {offset: 20, limit: 20}) {
+    id
+  }
+}
+```
+
+### Cursor Pagination
+
+Set the `start` value to zero to fetch the first page. Note that if the `start` parameter is omitted, offset-based pagination will be used by default.
+
+```
+query {
+  device_list(pagination: {start: 0, limit: 20}) {
+    id
+  }
+}
+```
+
+To determine the `start` value for the next page, add 1 to the primary key (`id`) of the last record in the previous page.
+
+For example, if the ID of the last record in the previous response was 123, we would specify a `start` value of 124:
+
+```
+query {
+  device_list(pagination: {start: 124, limit: 20}) {
+    id
+  }
+}
+```
+
+This will return up to 20 records with an ID greater than or equal to 124.

-Most API endpoints support an optional "brief" format, which returns only a minimal representation of each object in the response.

As an example, the default (complete) format of a prefix looks like this:
+A REST API response will include all available fields for the object type by default. If you wish to return only a subset of the available fields, you can append `?fields=` to the URL followed by a comma-separated list of field names. For example, the following request will return only the `id`, `name`, `status`, and `region` fields for each site in the response.
+
+```
+GET /api/dcim/sites/?fields=id,name,status,region
+```
+
+```json
+{
+    "id": 1,
+    "name": "DM-NYC",
+    "status": {
+        "value": "active",
+        "label": "Active"
+    },
+    "region": {
+        "id": 43,
+        "url": "http://netbox:8000/api/dcim/regions/43/",
+        "display": "New York",
+        "name": "New York",
+        "slug": "us-ny",
+        "description": "",
+        "site_count": 0,
+        "_depth": 2
+    }
+}
+```
+
+Similarly, you can opt to omit only specific fields by passing the `omit` parameter:
+
+```
+GET /api/dcim/sites/?omit=circuit_count,device_count,virtualmachine_count
+```
+
+!!! note "The `omit` parameter was introduced in NetBox v4.5.2."
+
+Strategic use of the `fields` and `omit` parameters can drastically improve REST API performance, as the exclusion of fields which reference related objects reduces the number and complexity of underlying database queries needed to generate the response.
+
+!!! note
+    The `fields` and `omit` parameters should be considered mutually exclusive. If both are passed, `fields` takes precedence.
+
+#### Brief Format
+
+Most API endpoints support an optional "brief" format, which returns only a minimal representation of each object in the response. This is useful when you need only a list of available objects without any related data, such as when populating a drop-down list in a form. It's also more convenient than listing out individual fields via the `fields` or `omit` parameters. As an example, the default (complete) format of a prefix looks like this:
 
 ```no-highlight
