Closes #19002: Module type profiles (#19014)

* Move Module & ModuleType models to a separate file

* Add ModuleTypeProfile & related fields

* Initial work on JSON schema validation

* Add attributes property on ModuleType

* Introduce MultipleOfValidator

* Introduce JSONSchemaProperty

* Enable dynamic form field rendering

* Misc cleanup

* Fix migration conflict

* Ensure deterministic ordering of attriubte fields

* Support choices & default values

* Include module type attributes on module view

* Enable modifying individual attributes via REST API

* Enable filtering by attribute values

* Add documentation & tests

* Schema should be optional

* Include attributes column for profiles

* Profile is nullable

* Include some initial profiles to be installed via migration

* Fix migrations conflict

* Fix filterset test

* Misc cleanup

* Fixes #19023: get_field_value() should respect null values in bound forms (#19024)

* Skip filters which do not specify a JSON-serializable value

* Fix handling of array item types

* Fix initial data in schema field during bulk edit

* Implement sanity checking for JSON schema definitions

* Fall back to filtering by string value

+# Module Type Profiles
+
+!!! info "This model was introduced in NetBox v4.3."
+
+Each [module type](./moduletype.md) may optionally be assigned a profile according to its classification. A profile can extend module types with user-configured attributes. For example, you might want to specify the input current and voltage of a power supply, or the clock speed and number of cores for a processor.
+
+Module type attributes are managed via the configuration of a [JSON schema](https://json-schema.org/) on the profile. For example, the following schema introduces three module type attributes, two of which are designated as required attributes.
+
+```json
+{
+    "properties": {
+        "type": {
+            "type": "string",
+            "title": "Disk type",
+            "enum": ["HD", "SSD", "NVME"],
+            "default": "HD"
+        },
+        "capacity": {
+            "type": "integer",
+            "title": "Capacity (GB)",
+            "description": "Gross disk size"
+        },
+        "speed": {
+            "type": "integer",
+            "title": "Speed (RPM)"
+        }
+    },
+    "required": [
+        "type", "capacity"
+    ]
+}
+```
+
+The assignment of module types to a profile is optional. The designation of a schema for a profile is also optional: A profile can be used simply as a mechanism for classifying module types if the addition of custom attributes is not needed.
+
+## Fields
+
+### Schema
+
+This field holds the [JSON schema](https://json-schema.org/) for the profile. The configured JSON schema must be valid (or the field must be null).
