feat: complete tables config — all tables, all fields, boolean type

- Add missing tables: languages, users, blocklist, user-names, users-public
- Fix categories field names (name_de → titel_de/en/sv)
- Add missing fields: objects_created, sentence_sv, answer, negative_statement_id, etc.
- Fix pairs answer_type options (yes_no/text/question/word)
- Add boolean field type support in RecordModal
