fix(i18n): translate pricing tiers, features, and content pages

Add name_translations JSON column to SubscriptionTier for multi-language
tier names. Pre-resolve tier names and build dynamic feature lists from
module providers in route handlers. Fix Jinja2 macro scoping by importing
pricing partial with context. Backfill content_translations for all 43
content pages across 4 platforms (en/fr/de/lb).
