VanChat

- Ended or cancelled events can now be scheduled again on a new date in the same Van — members, channels, and chat history all carry over, so nobody has to be re-invited (RSVPs reset for the new date) - Channels now recover on their own after a dropped connection instead of getting stuck on an error screen — cached content stays put and refreshes as soon as you're back - Images load more reliably everywhere: one that fails to appear now retries and refetches instead of leaving a permanent blank square - Video attachments are now checked for safety before they're shown, with a placeholder while that finishes - Broad security hardening across sign-in, uploads, and payments, including tighter limits on repeated login attempts and a fix for a privilege issue on specific desktop and mobile platforms
