fix: Frontend API Calls & Field Names für renamed tables

- Updated api.js function names:
  - listTrainingStyles → listStyleDirections
  - createTrainingStyle → createStyleDirection
  - updateTrainingStyle → updateStyleDirection
  - deleteTrainingStyle → deleteStyleDirection
  - listTrainingStyleTargetGroups → listStyleDirectionTargetGroups
  - createTrainingStyleTargetGroup → createStyleDirectionTargetGroup
  - updateTrainingStyleTargetGroup → updateStyleDirectionTargetGroup
  - deleteTrainingStyleTargetGroup → deleteStyleDirectionTargetGroup
  - getTrainingStylesHierarchy → getStyleDirectionsHierarchy
- Updated AdminCatalogsPage.jsx:
  - loadData() uses renamed API functions
  - CRUD functions renamed (createStyleDirection, etc.)
  - Matrix uses style_direction_id parameter
  - Hierarchy renders style_directions array
- Fixes data binding between frontend and backend after table rename

version: 0.4.0 (frontend)
module: AdminCatalogsPage 2.2.0
