fix(xlsx-s3): resolve Format name collision and correct multi-output assertion

- Use `using static ...Csv.Format` + `using static ...Xlsx.Format` in sample 02
  and the multi-output E2E test so Csv(...)/Xlsx(...) compile without the
  ambiguous `Format` class reference between the two format packages (ADR D16).
- Fix the multi-output E2E assertion: RecordsWritten counts distinct rows once
  (not per output); single-pass is proven by both output files being complete.
- ADR D14/D15/D16 recorded; plan.md PR4 test count corrected (34 green).
