feat: Add backend API endpoints for shipping method management

Phase 2 backend complete - Full CRUD for shipping methods.

New Endpoints:
 GET /methods/available - List all available shipping methods
 POST /zones/{id}/methods - Add method to zone
 DELETE /zones/{id}/methods/{instance_id} - Remove method
 GET /zones/{id}/methods/{instance_id}/settings - Get method form fields
 PUT /zones/{id}/methods/{instance_id}/settings - Update method settings

Features:
- Get available methods (Flat Rate, Free Shipping, etc.)
- Add any method to any zone
- Delete methods from zones
- Fetch method settings with current values
- Update method settings (cost, conditions, etc.)
- Proper error handling
- Cache clearing after changes
