adn8naiagent/F1ReplayTiming v1.2.1

Fix self-hosting connection and Docker URL issues

on GitHub

Fixes

• Connection error screen - when the frontend cannot reach the backend, a clear error message is now shown instead of the passphrase screen, with the attempted URL and troubleshooting tips
• Runtime API URL for Docker - NEXT_PUBLIC_API_URL can now be set as a runtime environment variable on the frontend container, so pre-built Docker images work with any backend URL without rebuilding. See the README for details
• Fixed loading overlay staying visible when navigating back to the session picker

New Features

• Red flag countdown and skip - during red flag periods in replay mode, a countdown timer shows how long until the session resumes, with a button to skip ahead to the restart
