Refactor CI workflow and enhance AdminBanSystem component

- Updated CI workflow to use 'dev' branch instead of 'develop' and renamed job from 'lint-and-typecheck' to 'lint-and-build'.
- Simplified linting and type checking steps in the CI process.
- Refactored switch cases in AdminBanSystem component for better readability and structure, ensuring consistent handling of API calls for various tabs.
