Switched to esbuild and bundle code into single file

ref https://linear.app/ghost/issue/AP-550/overhaul-docker-testing-setup

- with this change, we do away with `tsx` in favor of straight
  `esbuild`, as `tsx` was proving to be problematic with our boot time
- we can just compile this to a single JS file to keep this fast
- this also changes the Docker workflow to use this and concurrently to
  watch and reload the files
