Add Identities, Keyboard & Screen Readers and Reverse Proxy pages - Identities: where they're stored, backup/transfer via export/import, importing a TeamSpeak 3 .ini identity. - Keyboard & Screen Readers: Ctrl shortcuts, channel-tree keys, menus, dialogs, chat; what isn't available yet (push-to-talk). - Reverse Proxy: nginx/Caddy/Traefik/Cloudflare Tunnel examples, /ws WebSocket, TRUST_PROXY header handling, split client/gateway hosting. Linked from Home, FAQ and the configuration page. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Hu2cuPLqpuKVfd9wWFFakU
