Pull Request Overview

This PR adds filename and line number information to log statements in the benchmark dashboard and refactors the logging implementation. The changes simplify the logging architecture by removing the singleton BenchmarkLogger class and replacing it with a simpler module-level approach.

• Replaced singleton BenchmarkLogger class with a simpler module-level logger and initialization function
• Updated log formatter to include filename and line number information (<filename:line>)
• Updated import statements and function calls across files to use the new logging interface
