bun-sqlite's Database.transaction is synchronous, but async callbacks return
a pending Promise at the first await, causing immediate COMMIT before the
entire callback completes. This allowed partial inserts with no rollback.
Fixed by:
- Remove async from transaction callback
- Add .run() to each insert/update to execute synchronously
- Add regression test proving atomicity: transaction that throws mid-loop
rolls back all changes (both tables empty after failure)

- Add ConfirmDraftBody schema to shared types
- Implement GET /api/labs/drafts/:id (retrieves draft with extracted data)
- Implement POST /api/labs/drafts/:id/confirm (normalizes markers, inserts lab draw + biomarkers in transaction, marks draft confirmed)
- Implement POST /api/labs/drafts/:id/discard (marks draft discarded)
- Add comprehensive test suite with 3 new tests
