Add DE/EN language toggle with bilingual descriptions

Browse Source 
- Language switcher in sidebar (DE/EN buttons, persists to localStorage)
- i18n module with pick_desc/pick_name helpers for language-aware fallback
- All detail/list pages use language context for names and descriptions
- Species/Cultivar types updated with description_de/description_en
- Common Name column added to species/families lists
