fix: use unique temp filename for migration archive uploads

Plan to Eat exports CSV or TXT files directly, but the importer only accepted
ZIP archives. This caused a silent failure when users uploaded CSV files.

- Extend plantoeat_recipes() to detect ZIP vs CSV/TXT by magic bytes and
  process raw CSV/TXT files directly without requiring a ZIP wrapper
- Add _validate_archive() to return a clear error report entry when the
  uploaded file is neither a ZIP nor valid UTF-8 text
- Update frontend file input to accept .zip, .csv, and .txt
- Update i18n description to mention all accepted formats
- Add plantoeat.csv test fixture and integration tests for CSV import
  and invalid file type rejection
