fix: resolve 21 lint errors from GDPR/logger/caching commits and fix web lint

- Fix import ordering in auth DTOs, admin module, and test files
- Merge duplicate @modules/shared imports (no-duplicates with prefer-inline)
- Remove unused imports (ForceDeleteUserCommand, Inject)
- Use parameterless catch for unused error bindings
- Switch web lint from `next lint` to `eslint` (flat config compatibility)
