🐛 Fix terminal rendering issues on iOS Safari via DOM renderer

Switch ttyd's xterm.js renderer from the default WebGL/Canvas to the
DOM renderer using --client-option rendererType=dom.

WebGL rendering on iOS Safari is unreliable — it silently falls back or
produces garbled/invisible output. The DOM renderer trades a small
amount of rendering performance for broad browser compatibility.

Fixes #1016, #1026, #1027
