Species detail now shows a "Companion Plants" card (left column, after Ecology) with beneficial/antagonistic sub-lists. Each entry links to the companion species and shows the mechanism. Home page gains stats cards, quick-filter buttons, and a hero section. Species list supports URL query params for quick-filter links. New /api/v1/stats endpoint provides database counts. i18n keys added for DE/EN: card.companion_plants, companions.beneficial_for, companions.antagonistic_for, stat.*, filter.*, home.*.
