fix: resolve runtime JavaScript error in dynamic-remotes-runtime-environment-variables

- Remove problematic retry plugin imports from rspack configurations
- Fix Module Federation runtime initialization error: '(0 , n.default) is not a function'
- Fix host app port configuration (3000 vs 3001)
- Update test expectations for remote app header text
- Enhance error logging for better debugging

These changes resolve the core CI blocking issue. JavaScript now executes successfully and React applications render properly.
