Enhance end-to-end testing configuration and improve timeout handling. This update introduces a new e2e-test alias in the Cargo configuration for streamlined test execution. It also implements a scaled_timeout function to adjust test timeouts based on an environment variable, ensuring better control over test execution duration. Additionally, several tests are refactored to utilize cached metrics for improved performance and reliability.
