feat: Implement Phase 1 OMS with complete state machine
- Add OrderModels with all enums and records - Implement IOrderManager interface - Create BasicOrderManager with thread-safe state machine - Add INT8OrderAdapter interface for NT8 integration - Implement MockNT8OrderAdapter for testing - Add comprehensive unit tests (34 tests, all passing) - Full C# 5.0 compliance - >95% code coverage - Zero build warnings for new code Closes Phase 1 OMS implementation
