Backend scaffold test endpoints exposed in production without authentication

[andeplane]

Problem

backend/src/atomify_api/routers/test.py defines two unauthenticated endpoints:

• POST /test — writes arbitrary messages to the database
• GET /test — reads all test records from the database

These endpoints are unconditionally registered in main.py:

app.include_router(test_router)

This is scaffolding/boilerplate that was never removed. In production it allows anyone to write to the test_records table without any credentials.

Solution

Remove the test router and its associated model/migration from the codebase. If a DB connectivity check is needed in production, the existing /health endpoint is the right place for that.
