Integriert die Feature-Branch (Dark Mode, i18n DE/EN, mobile Admin-Layout,
shared admin_nav, Toasts, Voucher-Templates, Bulk-Erstellung, konfigurierbare
Defaults, Password-Reset, Audit-Log-UI + Audit-Logging) mit der bestehenden
Security-/Updater-Arbeit.
Konfliktauflösung (6 Dateien: index.php + admin/*): Feature-Version als Basis,
darauf die Security-Patches re-appliziert:
- display_errors=0 + log_errors in allen neuen/gemergten Entry-Points
- Crypto::encrypt/decrypt an allen Site-Passwort-Pfaden (sites/index/vouchers/
dashboard-Sync, inkl. doCreateVoucher + Bulk)
- CSRF-Prüfung für ALLE Voucher-Erstellungen (auch anonym/öffentlich), Token
unbedingt im Formular; Session-Throttle gegen Spam
- Updater-Maintenance-Hook am Anfang von index.php wiederhergestellt
Auto-Merge verifiziert: Auth.php enthält Session-Timeout UND writeAuditLog;
login.php behält display_errors=0 + OAuth-state. Updater-Link in shared
admin_nav.php (i18n-Key nav_update DE/EN). Alle PHP-Dateien linten sauber.
- m365_callback.php: OAuth-state-Validierung gegen Login-CSRF
- includes/Crypto.php: Verschlüsselung-at-rest für UniFi-Passwörter
(AES-256-GCM/libsodium) mit Klartext-Fallback für Bestandsinstallationen
- install.php: APP_KEY-Generierung + Reinstall nur mit Admin-Session
- Auth.php: absolutes Session-Timeout (SESSION_LIFETIME) durchsetzen
- index.php: CSRF + Throttle auch für anonyme öffentliche Voucher-Erstellung
- UniFiController.php: createVoucher liefert nicht mehr den falschen Code
bei parallelen Erstellungen (note-Match statt blindes reset())
- display_errors in allen Entry-Points deaktiviert, log_errors aktiviert
- test.php & m365_debug.php hinter requireAdmin() (Info-Leak)
- m365_debug.php: abgeschnittene/kaputte Datei vervollständigt
- Dark mode: CSS custom properties (global.css) + toggle button, persisted in localStorage
- i18n: German/English language switcher (lang/de.php, lang/en.php, includes/I18n.php)
- Mobile-responsive admin layout: hamburger menu, sidebar overlay (global.js + global.css)
- Shared admin navigation include (includes/admin_nav.php) used across all admin pages
- Toast notifications system globally available via global.js
- Voucher templates/profiles: CRUD UI at admin/templates.php with voucher_templates DB table
- Bulk voucher creation: create 1-20 vouchers at once with multi-print layout on index.php
- Configurable voucher defaults: expire time, device limit, max limit in admin settings
- Template quick-select on voucher form: auto-fills max_uses and expire_minutes
- Password reset flow: forgot_password.php + reset_password.php with token-based reset
- Audit log UI: admin/audit_log.php with filter, pagination, audit_log DB table
- Audit logging on login, user create/edit/delete, site create/edit/delete
- Admin pages updated: index, vouchers, users, sites all use admin_nav.php + dark mode + i18n
- Voucher admin: live search input added alongside existing status filter + pagination
- Users admin: password-reset-link button per user row (when SMTP enabled)
- Login page: i18n, dark mode, language switcher, forgot password link

Bug fixes:
- UniFiController: add CURLOPT_TIMEOUT (10s) and CURLOPT_CONNECTTIMEOUT (5s)
to login() and apiRequest() — prevents page freeze when controller unreachable
- UniFiController: fix login response validation for UniFi OS API which returns
a user object instead of meta.rc=ok
- admin/sites.php: add JS loading state on form submit to give visual feedback
- login.php: handle new 'rate_limited' return value from Auth::login()
New features:
- Database: in-memory settings cache eliminates redundant DB queries per request
- Auth: login rate limiting (10 attempts per 10 min per IP/email) via login_attempts table
- admin/vouchers.php: CSV export with UTF-8 BOM for Excel compatibility
- admin/vouchers.php: client-side pagination (50 per page)
- index.php: QR code display after voucher creation (qrcodejs CDN)
- Mailer: sendTestEmail() method
- admin/settings.php: SMTP test button with AJAX handler
- database.sql: add login_attempts and audit_log tables
