Update Settings Reference: clarify removal of custom CSS/JS fields and provide alternatives
Add the wiki: install, themes, settings, troubleshooting, support Six pages plus a sidebar and footer, replacing the placeholder Home page. Written against what the app actually does rather than from the README: the settings tables are taken from the DocType field by field, and the troubleshooting page covers the failure modes this app has genuinely had — stale cached CSS looking identical to a broken theme, a silent migrate when redis is down, realtime updates needing socket.io, and no audio shipping with the sound feature. Contact details on the Support page and in the footer.
