v2026-02-11.1

Added

• Incident Report Export: Two-step flow — editable ISP complaint letter with customer data fields + downloadable technical PDF report with channel tables, worst values, and DIN threshold references
• Report i18n: Full PDF report localization in 4 languages (EN/DE/FR/ES) with locale-appropriate regulatory authorities (Bundesnetzagentur, ARCEP, etc.)
• Language selector in topbar: Country flag dropdown (🇬🇧🇩🇪🇫🇷🇪🇸) for quick language switching
• BQM setup guide: Sidebar link always visible; when not configured, opens modal with benefits and step-by-step setup instructions (DynDNS, WAN ping, ThinkBroadband registration)
• Bundled DejaVu fonts: PDF generation works in Docker without host font dependencies

Changed

• Settings moved to sidebar bottom: Following common UI convention
• Report modal redesign: Split into complaint letter (copyable text) + technical report (PDF attachment) for easier ISP communication

Fixed

• BQM modal HTML rendering: i18n strings with HTML tags now render correctly via Jinja2 safe filter
