Fix cron routes: POST → GET (Vercel cron sends GET)
Our drip email cron ran its first day and sent zero emails. The cron hit the endpoint, got a 200 back, everything looked healthy. Turns out Vercel cron sends GET requests, but we put the email logic in a POST handler. The GET handler was just a health check returning {"status":"healthy"}. Two of three cron routes had this bug - the third one happened to use GET and worked fine. I'm not sure what's more depressing about this. NodeJS bros recreating the "curl via http request" bullshit that was the scourge of shared hosting php 20 years ago; or Deploying something to production that has never been tested even once, and then pretending it's the platform hosts' fault for doing something you didn't anticipate.
