A cleaner, calmer composer

The chat composer got a full redesign:

• One quiet frame. Softer corners, a lower profile, and every control in calm ink - the send button is the only thing that lights up.
• Notices slide out from behind. Credit warnings no longer stack a banner on top of the chat box; they dock behind it as a slim strip, so the composer always stays in front.
• Compact attachments. Files and images you attach are now small chips inside the frame instead of large preview cards.
• Little touches. A frosted-glass scroll-to-bottom button, a clearer sidebar icon, and a bit more breathing room in the header - especially on phones.
