Project Assistant: rename chats, see who owns each assistant, and a tidier context block

A handful of Project Assistant improvements land together: rename conversations inline as you work, see at a glance who owns each assistant, and keep the chat clean with app-injected context folded into a collapsible disclosure.

Features

• Rename assistant chats from the live chat view #3649  - The dock header shows the active conversation’s title and lets you click to rename it inline. Names you set are kept — automatic title generation skips any chat you’ve renamed, and clearing the title re-enables auto-naming. (Author: @simplesagar )
• See who owns each assistant #3709  - An assistant’s creator is now shown as its owner — an avatar and name on both the assistant card and the setup page — resolving to the creating member, “No owner” when never attributed, or “Orphaned, no owner” when the creator has left the organization.

• Tidier injected context in assistant chats #3721  - App-injected context in a user turn now folds into a collapsed Additional context disclosure you can expand to inspect, instead of rendering the raw tags, and the expanded block wraps to the message width so opening it no longer widens the bubble.
