Generate page: - Full form with passphrase word count slider, PIN/RSA toggles - Credential display with copy buttons, QR code, entropy breakdown - Channel key generation accordion - Added QR code routes (generate_qr, generate_qr_download) - Added RSA key download route (download_key) - Fixed route name: encode_page → encode Tools page: - Image capacity checker, EXIF viewer/editor, rotation, compression - Format conversion, image comparison - (API routes for tools pending — UI renders but actions need backend) Admin users page: - User table with role badges, creation dates - Add/delete/reset password actions - Fixed route names to match soosef conventions - Added user_count and current_user to template context Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
