refactor: clean up duplicate imports and dead code

- Merge type and value imports from the same module into single imports
- Remove dead import-badges action (flow uses /api/admin/import/badges)
- Remove unused babel-plugin-react-compiler devDependency
- Remove stray test.txt file
- Update knip config: track css imports, drop redundant ignore entries
- Update contract test to drop obsolete dead-action assertion
