refactor: consolidate validateParams and remove unused config

- Import validateParams from shared utility in discussions.js, locations.js, and organization.js
- Remove duplicate validateParams implementations (DRY principle)
- Remove unused ghClientSecret export from config.js
- Reduces code by 28 lines while maintaining 100% test coverage
