chore: remove external deps and add fetch client

[csecrestjr]

Summary

• replace axios calls with a small fetch-based http client
• drop bcrypt, jwt, and other npm packages by using Node's crypto and optional requires
• fallback to a minimal HTTP server when Express isn't installed

Testing

• timeout 10 npm install --omit=dev --no-progress
• npm test
• node server.js
