Pull Request Overview

This PR fixes client connection issues by standardizing request paths and updating dependency versions.

• Replaced hardcoded "/" paths with empty strings in HTTP client calls for post, get, and delete.
• Bumped the http package to 2.14.2 and mcp to 0.4.3, and added io and log modules in Dependencies.toml.
• Updated the mcp version and native JAR path to the new snapshot in Ballerina.toml.

• I don't see any new tests covering the behavior when the request path is an empty string. Consider adding unit or integration tests to verify that post, get, and delete with an empty path function correctly against target servers.
