fix(ci): build shared packages before tests and fix formatting

- Add build:packages step to all test.yml jobs (fixes @manacore/shared-nestjs-auth not found)
- Handle missing coverage artifacts gracefully in test-coverage.yml
- Update .prettierignore to exclude apps-archived/ and problematic files
- Format all source files to pass CI checks
