Unit test set up - Research QUnit and GasT for unit test implementation

## Overview
As part of addressing technical debt for the Hack for LA Tables project, we need to implement unit testing to ensure the reliability of our onboarding/offboarding automation system (built with Google Apps Script). This issue tasks is to research QUnit and GasT for unit test implementation, documenting findings, and proposing a setup plan to improve code quality.

## Action Items
- [ ] **Research QUnit for Google Apps Script**:
- Investigate QUnit’s compatibility with GAS, focusing on testing scripts like `project_onboarding.gs`, `bot.gs`, and `ZoomAttendeeReport.gs`.
- Identify setup requirements (e.g., library integration, test runner configuration).
- Document advantages, limitations, and examples (e.g., testing `projectOnboardingAutomation`).
- [ ] **Research GasT for Google Apps Script**:
- Explore GasT’s features for GAS unit testing, including setup and integration with our CI/CD pipeline (GitHub Actions, `clasp`).
- Compare GasT with QUnit for ease of use, coverage, and community support.
- Provide sample test cases for key functions (e.g., `getRolePermission`, `setTrigger`).
- [ ] **Document findings** below
