Add ProductKit binding to ConfigurableKitProductAttribute values

Implementation of kit binding feature for ConfigurableKitProduct variants:

- Added ForeignKey field `kit` to ConfigurableKitProductAttribute
  * References ProductKit with CASCADE delete
  * Optional field (blank=True, null=True)
  * Indexed for efficient queries

- Created migration 0007_add_kit_to_attribute
  * Handles existing data (NULL values for all current records)
  * Properly indexed for performance

- Updated template configurablekit_form.html
  * Injected available ProductKits into JavaScript
  * Added kit selector dropdown in card interface
  * Each value now has associated kit selection
  * JavaScript validates kit selection alongside values

- Updated JavaScript in card interface
  * serializeAttributeValues() now collects kit IDs
  * Creates parallel JSON arrays: values and kits
  * Stores in hidden fields: attributes-X-values and attributes-X-kits

- Updated views _save_attributes_from_cards() in both Create and Update
  * Reads kit IDs from POST JSON
  * Looks up ProductKit objects
  * Creates ConfigurableKitProductAttribute with FK populated
  * Gracefully handles missing kits

- Fixed _should_delete_form() method
  * More robust handling of formset deletion_field
  * Works with all formset types

- Updated __str__() method
  * Handles NULL kit case

Example workflow:
  Dlina: 50 -> Kit A, 60 -> Kit B, 70 -> Kit C
  Upakovka: BEZ -> Kit A, V_UPAKOVKE -> (no kit)

Tested with test_kit_binding.py - all tests passing
- Kit creation and retrieval
- Attribute creation with kit FK
- Mixed kit-bound and unbound attributes
- Querying attributes by kit
- Reverse queries (get kit for attribute value)

Added documentation: KIT_BINDING_IMPLEMENTATION.md
