Implement M2M architecture for ConfigurableKitProduct variants with dynamic attribute selection

This commit introduces a complete refactoring of the variable product system:

1. **New Model**: ConfigurableKitOptionAttribute - M2M relationship between variants and attribute values
   - Replaces TextField-based attribute storage with proper database relationships
   - Ensures one value per attribute per variant through unique_together constraint
   - Includes indexes on both option and attribute fields for query performance

2. **Form Refactoring**:
   - Removed static 'attributes' field from ConfigurableKitOptionForm
   - Added dynamic field generation in __init__ based on parent attributes
   - Creates ModelChoiceField for each attribute (e.g., attribute_Длина, attribute_Упаковка)
   - Enhanced BaseConfigurableKitOptionFormSet validation to check all attributes are filled

3. **View Updates**:
   - Modified ConfigurableKitProductCreateView.form_valid() to save M2M relationships
   - Modified ConfigurableKitProductUpdateView.form_valid() with same logic
   - Uses transaction.atomic() for data consistency

4. **Template & JS Enhancements**:
   - Reordered form so attributes section appears before variants
   - Fixed template syntax: changed from field.name.startswith to "attribute_" in field.name
   - Updated JavaScript to dynamically generate attribute select fields when adding variants
   - Properly handles formset naming convention (options-{idx}-attribute_{name})

5. **Database Migrations**:
   - Created migration 0005 to alter ConfigurableKitOption.attributes to JSONField (for future use)
   - Created migration 0006 to add ConfigurableKitOptionAttribute model

6. **Tests**:
   - Added test_configurable_simple.py for model/form verification
   - Added test_workflow.py for complete end-to-end testing
   - All tests passing successfully

Features:
✓ All attributes required for each variant if defined on parent
✓ One value per attribute per variant (unique_together constraint)
✓ One default variant per product (formset validation)
✓ Dynamic form field generation based on parent attributes
✓ Atomic transactions for multi-part operations
✓ Proper error messages per variant number

+# ConfigurableKitProduct Implementation Summary
+
+## Overview
+Successfully implemented a complete variable product system for binding multiple ProductKits to attribute value combinations. The system allows creating variable products with attributes and dynamically selecting ProductKits for each variant.
+
+## Changes Made
+
+### 1. Database Models ([products/models/kits.py](myproject/products/models/kits.py))
+
+#### ConfigurableKitOptionAttribute Model (NEW)
+- **Purpose**: M2M relationship between ConfigurableKitOption variants and ConfigurableKitProductAttribute values
+- **Fields**:
+  - `option`: ForeignKey to ConfigurableKitOption (with related_name='attributes_set')
+  - `attribute`: ForeignKey to ConfigurableKitProductAttribute
+- **Constraints**:
+  - unique_together: ('option', 'attribute') - ensures one value per attribute per variant
+  - Indexed on both fields for query performance
+
+#### ConfigurableKitOption Model (UPDATED)
+- **Removed**: TextField for attributes (replaced with M2M)
+- **Relationship**: New reverse relation `attributes_set` through ConfigurableKitOptionAttribute
+
+### 2. Database Migrations ([products/migrations/0006_add_configurablekitoptionattribute.py](myproject/products/migrations/0006_add_configurablekitoptionattribute.py))
+
+- Created migration for ConfigurableKitOptionAttribute model
+- Applied successfully to database schema
+
+### 3. Forms ([products/forms.py](myproject/products/forms.py))
+
+#### ConfigurableKitOptionForm (REFACTORED)
+- **Removed**: 'attributes' field from Meta.fields
+- **Added**: Dynamic field generation in __init__ method
+  - Generates ModelChoiceField for each parent attribute
+  - Field names follow pattern: `attribute_{attribute_name}`
+  - For edit mode: pre-populates current attribute values
+- **Example**: If parent has "Длина" and "Упаковка" attributes:
+  - Creates `attribute_Длина` field
+  - Creates `attribute_Упаковка` field
+
+#### BaseConfigurableKitOptionFormSet (ENHANCED)
+- **Added**: Comprehensive validation in clean() method
+  - Checks for duplicate kits
+  - Validates all attributes are filled for each variant
+  - Ensures max one default variant
+  - Provides detailed error messages per variant number
+
+#### Formsets (UPDATED)
+- ConfigurableKitOptionFormSetCreate: extra=1, fields=['kit', 'is_default']
+- ConfigurableKitOptionFormSetUpdate: extra=0, fields=['kit', 'is_default']
+
+### 4. Views ([products/views/configurablekit_views.py](myproject/products/views/configurablekit_views.py))
+
+#### ConfigurableKitProductCreateView.form_valid() (UPDATED)
+- Iterates through option_formset
+- Saves ConfigurableKitOption with parent
+- Creates ConfigurableKitOptionAttribute records for each selected attribute
+- Uses transaction.atomic() for data consistency
+
+#### ConfigurableKitProductUpdateView.form_valid() (UPDATED)
+- Same logic as Create view
+- Properly deletes old attribute relationships before creating new ones
+
+### 5. Template ([products/templates/products/configurablekit_form.html](myproject/products/templates/products/configurablekit_form.html))
+
+#### Form Structure (REORDERED)
+- Attributes section now appears BEFORE variants
+- Users define attributes first, then bind ProductKits to attribute combinations
+
+#### Dynamic Attribute Display
+- Variant form rows iterate through dynamically generated attribute fields
+- Renders select dropdowns for each attribute field
+- Field names follow pattern: `options-{formIdx}-attribute_{name}`
+
+#### JavaScript Enhancement
+- addOptionBtn listener dynamically generates attribute selects
+- Clones structure from first form's attribute fields
+- Properly names new fields with correct formset indices
+
+### 6. Test Scripts (NEW)
+
+#### test_configurable_simple.py
+- Verifies models and relationships exist
+- Checks form generation
+- Validates view imports
+
+#### test_workflow.py
+- Complete end-to-end workflow test
+- Creates ConfigurableKitProduct
+- Creates attributes with multiple values
+- Creates variants with M2M attribute bindings
+- Verifies data retrieval
+
+**Test Results**: All tests PASSED ✓
+- Successfully created 3 variants with 2 attributes each
+- All data retrieved correctly through M2M relationships
+- Form validation logic intact
+
+## Usage Workflow
+
+### Step 1: Create Variable Product
+1. Go to /products/configurable-kits/create/
+2. Enter product name and SKU
+3. Define attributes in the attributes section:
+   - Attribute Name: e.g., "Длина"
+   - Attribute Values: e.g., "50", "60", "70"
+
+### Step 2: Create Variants
+1. In variants section, for each variant:
+   - Select a ProductKit
+   - Select values for each attribute
+   - Mark as default (max 1)
+2. Form validates:
+   - All attributes must be filled
+   - No duplicate kits
+   - Only one default variant
+
+### Step 3: Save
+- System creates:
+  - ConfigurableKitOption records
+  - ConfigurableKitOptionAttribute relationships
+  - All in atomic transaction
+
+## Data Structure
+
+```
+ConfigurableKitProduct (parent product)
+├── parent_attributes (ConfigurableKitProductAttribute)
+│   ├── name: "Длина", option: "50"
+│   ├── name: "Длина", option: "60"
+│   ├── name: "Упаковка", option: "БЕЗ"
+│   └── name: "Упаковка", option: "В УПАКОВКЕ"
+│
+└── options (ConfigurableKitOption - variants)
+    ├── Option 1: kit=Kit-1
+    │   └── attributes_set (ConfigurableKitOptionAttribute)
+    │       ├── attribute: Длина=50
+    │       └── attribute: Упаковка=БЕЗ
+    │
+    ├── Option 2: kit=Kit-2
+    │   └── attributes_set
+    │       ├── attribute: Длина=60
+    │       └── attribute: Упаковка=В УПАКОВКЕ
+    │
+    └── Option 3: kit=Kit-3
+        └── attributes_set
+            ├── attribute: Длина=70
+            └── attribute: Упаковка=БЕЗ
+```
+
+## Key Features
+
+✓ **M2M Architecture**: Clean separation between attribute definitions and variant bindings
+✓ **Validation**: Ensures all attributes present for each variant
+✓ **Dynamic Forms**: Attribute fields generated based on parent configuration
+✓ **Data Consistency**: Atomic transactions for multi-part operations
+✓ **User-Friendly**: Attributes section appears before variants in form
+✓ **Flexible**: Attributes can be reordered and positioned
+
+## Notes
+
+- All attributes are REQUIRED for each variant if defined on parent
+- Maximum ONE value per attribute per variant (enforced by unique_together)
+- Maximum ONE default variant per product (enforced by validation)
+- No backward compatibility with old TextField attributes (intentional - fresh start)
+- Supports any number of attributes and values
+
+## Testing
+
+Run the test scripts to verify implementation:
+
+```bash
+cd myproject
+python test_configurable_simple.py  # Basic model/form tests
+python test_workflow.py              # Full workflow test
+```
+
+Both tests should pass with "OK: ALL TESTS PASSED!" message.
