chore: Update Docker configuration, API, and liquidity handling
- Changed Docker Compose to use host networking for services. - Updated API to enable CORS and modified PostgreSQL and Redis host configurations. - Refactored Dockerfile to build a single binary for the API server. - Introduced a rebalance cron job in the agent package for periodic execution. - Enhanced liquidity service to retrieve total pool liquidity and updated related API responses. - Added new vault API routes for fetching vault state and positions, including liquidity details. - Improved error handling and logging throughout the API and service layers.
