Update the workflow to extract test statistics from vitest's default reporter output in test-output.txt, replacing the previous JSON reporter parsing. This ensures test metrics are still collected and reported even when the JSON reporter is not used.
Introduced a Vitest-based backend unit testing framework with supporting scripts, helpers, and GitHub Actions integration. Refactored the admin settings page to a modular architecture, splitting monolithic logic into feature-specific tabs and hooks for improved maintainability and testability. Updated documentation to reflect the new testing setup and settings architecture, and added new dependencies for testing utilities.
