feat(plantare): usable UI — commitments screen, add sheet, entry points

The reproduction-commitment (Plantare) UI, local-first and plain-spoken:
- A Plantares screen (drawer entry, /plantares) listing your commitments,
  grouped Open / Done, with a big 'mark returned', a menu (let it go / reopen
  / remove) and an empty-state that explains what a Plantare is.
- An add sheet (scrollable): a two-choice 'who reproduces & returns' (I return
  / owed to me), an optional 'with whom', an optional 'what comes back' in the
  grower's own words, and a note. No sale, no currency — a promise.
- Reachable from a seed too: an 'Add a commitment' action on the variety
  detail, pre-attached to that variety.
- i18n en/es/pt/ast (human words: 'Plantare' + a plain explanation).

Added the Plantares screen to the small-phone overflow guard (18 cases green).
