Add Oracle Aggregator and CCIP Integration

- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control.
- Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities.
- Created .gitmodules to include OpenZeppelin contracts as a submodule.
- Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment.
- Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks.
- Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring.
- Created scripts for resource import and usage validation across non-US regions.
- Added tests for CCIP error handling and integration to ensure robust functionality.
- Included various new files and directories for the orchestration portal and deployment scripts.
