Make Docker dev containers compatible for NERSC Spin

[tomvothecoder]

Description

• Closes [DevOps] Make Docker dev setup compatible with NERSC Spin #67

Steps to Complete

Backend

1. Dockerfile
   • Remove appuser setup
     • Causes issues with root ownership of app data on Spin
     • Told it was probably okay to remove but need to follow up with John Riner for confirmation
2. config.py
   • Accept OS environment variables (set on Rancher), in addition to env file (for local dev)
3. Rancher environment variables
   • SSL/cert setup
   • Frontend origin and redirect setup
   • Authentication setup -- create another OAuth app on GitHub

Frontend

1. Dockerfile
   • Remove node_modules mounting for hot reload
     • Error where incorrect node_modules is referenced on Spin (requires volume mount, which is unnecessary)
2. nginx-backend-not-found.conf
   • Encapsulate location blocks inside server{...}
3. package.json
   • Fix TypeScript issues
     • vite build runs tsc -b which breaks due to TypeScript issues
4. vite.config.ts
   • Update certificate setup which reads from a local path -- ingress handles this
