Fix type errors caught by ty check

- Add type: ignore comments for external library type stub limitations
  (csv.reader, click.progressbar, IOBase.name, Callable.__name__)
- Change Iterable to Sequence for SQL where_args parameters
- Use db.table() instead of db[name] for proper Table return type
- Fix rebuild_fts return type from None to Table
- Update test_tracer to expect fewer queries (optimization side effect)
