Vercel Platforms Launch and Fixes

Creating this release as a starting point for using this process going forward. This code has already been deployed to production.

v1.0.0 of the platform is multi-tenant, supporting many TNC orgs in one Vercel project instead of previously requiring one project per organization. It also contains the first week's worth of post-launch bugfixes and adjustments.

This also includes one new feature: Instagram Reels are now supported as embeds in articles.
