- Move mic-blocked warning into conv-chat-window (prepend) so it scrolls
with the chat instead of pushing the input bar off-screen
- Remove min-height:400px from conv-chat-window; give conv-chat-panel a
viewport-relative height so the input bar is always visible at the bottom
- loader.js: append ?v=<timestamp> to section fetches to bust browser cache
(was serving stale s-conversation.html after updates)
