Migrate database server (EC2) to hosted database service (that is MySQL compatible)

[thescientist13]

As part of #28 , it should be worth considering moving off the EC2 instance currently running into something more managed, like a PlanetScale, or similar. Assuming pricing is at least equal, this would help ensure the current server doesn't ever age out or crash.

Something like this would also provide a nice browser based way to manage data updates as well, instead of having to build a custom dashboard.

This would also be a good way to potentially test Greenwood with something like this when combined with #32 .

4. Setup web hooks for automated cache busting (this was always manual, so sounds like just a new standalone feature?) - deferred to automate and document caching strategy #34
