v2.59.3

• 2.59.3 — ⚡ Scale-audit performance fixes. A simulated commercial
  grow (2,800 plants, 40,000 logs, 500 seed packets) found the Plants page
  taking 104s and the Costs page 22s to load. Fixed: a reminders-endpoint
  N+1 (82.7s → 0.25s, output verified byte-identical), a per-card cover-photo
  request storm (one bulk /api/plants/covers call now), half a million
  eagerly-rendered packet checkboxes on the Costs page (now built lazily on
  open), and ~2,200 per-row packet-link requests (bulk endpoints). Plants
  loads in ~8s, Costs in ~8s. Everything else scaled fine.
