Review UX Improvements

• Evaluation verdict in the sidebar. The Review section's progress line now shows the verdict (Valid and Sound, Fails, etc.) alongside the claim and premise counts once you complete a review.
• Review status badge. The Review icon in the sidebar (both collapsed rail and expanded accordion) now shows a small status badge: a blue icon when the review hasn't started, a yellow warning when it's in progress, and a green check when it's complete.
• Review guidance modal. When you open a published argument for the first time, a modal encourages you to start a review. It shows an estimated time and your progress. You can suppress it per-argument or globally.
• Maximize Details bug fix. Clicking "Maximize Details" while a node was selected no longer immediately collapses the sidebar back.
• Review button sizing. The Start/Continue/Edit Review button is now 90% width and centered for a cleaner look.

Persistent Reviews

• Reviews are now saved to the server. When you're signed in, your review assignments are automatically synced to the database. You can start a review on one device and pick it up on another.
• Review deep links. Navigate directly to a review via /view/{id}/{v}/review (redirects to your latest review) or /view/{id}/{v}/review/{reviewId}.
• Sidebar timestamps. The Review section now shows "Created" and "Last updated" timestamps when a server-backed review exists.
• Local-to-server promotion. If you started a review while signed out and then sign in, your local progress is automatically promoted to the server.
