thinking of a new approach here:

1. build all images on github/fast caching
2. run defined workflow (we'll move into code), which does the pipeline rollout+migrations

that removes the complexity of calling each service/etc from here, and realistically our only goal was to manage the docker aspect to optimize layer caching

https://github.com/northflank/deploy-to-northflank/blob/main/index.ts

we could just create a new action based on this that has "trigger-workflow" or similar

i was goingg to abandon this, but i think we're still better off if this is managed in github

it ensures we have easy access to run scripts/etc like discord notifications
