Update dependencies and refactor loading components

- Removed `react-is` and `require-in-the-middle` overrides from `package.json` and `pnpm-lock.yaml`.
- Updated various dependencies across multiple packages, including `@types/node` to `^24.5.2`, `react-hook-form` to `^7.63.0`, and `@ai-sdk/openai` to `^2.0.32`.
- Deleted the `loading.tsx` component from the admin accounts directory, streamlining the codebase.
- Adjusted `playwright.config.ts` to use a configurable number of workers for CI environments, enhancing test performance.
- Improved error handling in user ban and reactivation dialogs to provide clearer feedback to the admin user.
