fix: chat not opening after SAS in v4.8.14 (nowTick scope) — v4.8.15

The new composer props (nowTick, codeMode, view-once/timer setters, unsend/expire
handlers) were threaded into EnhancedConnectionSetup, but the message list and
composer live in the sibling EnhancedChatInterface. After SAS confirmation the
verified-state re-render referenced an out-of-scope `nowTick`, throwing
"ReferenceError: Can't find variable: nowTick" so the chat never rendered.

Move the prop destructuring and pass-through onto EnhancedChatInterface (where the
chat UI actually is) and revert the mistaken additions on EnhancedConnectionSetup.
No behavioural change to the v4.8.14 features otherwise. Bumps to 4.8.15.
