fix(agent): Ensure agent receives and applies dynamic config on startup

This commit fixes a bug where the agent would not receive its dynamic, server-side configuration upon initial connection. It now correctly fetches the effective configuration during the handshake process.

Key changes:
- Modified the server's handshake logic in `core_services.rs` to call `get_effective_vps_config` and send the correct configuration to the agent immediately after connection, replacing the previously used hardcoded default config.
- Added logging in the agent (`agent.rs`, `metrics.rs`) to print the received configuration and log configuration check intervals, improving debuggability.
- Refactored `get_effective_vps_config` in `config_routes.rs` to accept a `&DatabaseConnection` instead of the full `Arc<AppState>`, making it more modular and reusable.
