Phase 0: Update credit costs and CreditService, add credit checks to AI Engine
- Updated CREDIT_COSTS to match Phase 0 spec (flat structure) - Added get_credit_cost() method to CreditService - Updated check_credits() to accept operation_type and amount - Added deduct_credits_for_operation() convenience method - Updated AI Engine to check credits BEFORE AI call - Updated AI Engine to deduct credits AFTER successful execution - Added helper methods for operation type mapping and amount calculation
