The 'giving all with payment and promise' widget test awaited
repo.watchSales().first / watchPlantares().first in its body. A Drift
stream's .first never completes under the widget-test fake-async clock
(pumpAndSettle has already returned, so dart_test.yaml's per-test timeout
can't bound it), so the test hung to the framework's 10-min hard cap.
- Read the recorded sale/plantare with one-shot db.select(...).get()
queries instead (same filter, resolves fine under fake-async) — the
suite now passes in ~1s.
- Add a pure-Dart guard test that scans test/ui/ and fails loudly if any
awaited watchX().first reappears, so this stops being recurrent.
'Seeds changed hands' is now the single entry point on the variety
detail (and per lot row): direction (gave/received), one-tap 'all of it'
(default — the whole-plant/shrub case), optional partial quantity,
counterparty, and reveal-on-tap money and return-promise sections that
spawn the Sale/Plantare rows through recordHandover in one save.
Zero-lot varieties still work (ledger rows only); several lots get a
chip picker. The Sales/Plantares screens keep their own add buttons for
off-app records — the sheets stay, demoted to secondary.
i18n handover block in en/es/pt/ast; widget tests for the flow.
