What is in this PR?

Adds a QR code to the presentation view that participants can scan to join the event directly, shown by default so a
presenter doesn't have to remember to open it. Lives in the presentation header rather than the bot presence panel, so
it doesn't compete with the bot's video for space.

Changes in the codebase

• components/PresentationHeader.tsx: new participantUrl prop. When present, adds a QR-code toggle icon button next to
  the theme toggle, opening a Popover anchored to that button. The popover is open by default (useState(true)) and the
  same button hides/re-shows it afterward. Anchored bottom-right of the button, so it opens on top of the bot presence
  panel rather than the chat/transcript area.
• hooks/useConversationSetup.ts: exposes participantUrl (from conversation.eventUrls.participant[0].url).
• pages/assistant.tsx: passes participantUrl through to PresentationHeader.

Documentation and automated testing

Did you:

• document any breaking changes in your commit messages?
• document your changes as comments in the code? Use TSDoc format where appropriate.
• update the README and docs to be clear and easy to use for end users and developers?
• add and/or update automated tests?
• update team documentation of any new or changed environment variables?
• If openapi.json changed: names the llm_engine PR/commit it came from, and whether that backend change is deployed
• add a What's New entry in content/whatsNew.ts for new features?

Testing this PR

• Open the presentation view for an event with a participant join link and confirm the QR code (+ "Scan to join"
  label) is visible immediately, with no click needed.
• Click the header's QR toggle button and confirm the popover closes; click it again and confirm it reopens.
• Confirm the toggle button is hidden entirely for an event with no participant link.
• Confirm the rest of the page (chat, bot panel, theme toggle) stays fully clickable while the QR popover is open.

Additional information

This builds on top of the bot presence panel PR (jh/bot-presentation-view) — rebase/merge that one first. One
accessibility nuance worth knowing: MUI's Popover marks the rest of the page aria-hidden while open (standard modal
plumbing, confirmed this MUI version doesn't also apply the native inert attribute), so mouse/touch interaction with
the rest of the page is unaffected, but a screen reader wouldn't see the header's other controls — including the toggle
button itself — while the QR is showing.
