Add four DB-backed configuration tables for site-wide settings: site_settings (logo, top-left title, header/footer text with zh/en variants), upload_configs (master switch, default size, storage dir), upload_file_types (per-extension whitelist with per-type size limits), and download_baseurls (multiple download sources with priority/default). - Models, AutoMigrate, and first-run seed (18 common file types) - Process-level config cache warmed at startup, refreshed on admin save - SetUserContext injects cached site settings into templates - base.html renders logo (local upload or external URL), title, header banner, and footer with i18n fallback - Upload validator drives avatar uploads (form + AJAX) through the configured switch/type/size policy - Admin pages for site/upload/download settings with i18n keys Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
