Add e2e coverage for the backup API: no end-to-end spec exercises backup, restore, or status

Labels / Complexity: testing · Medium Complexity — Medium

Problem

The test/e2e/ suite has no spec for the backup API. The backup/restore/status endpoints manage database snapshots — the data-loss boundary — and only unit specs cover fragments of the service (#86). With #42 (ephemeral archives) pending, there is no HTTP-level guard on backup behavior.

Why this is architecturally hard

1. Restore is destructive. An e2e restore test must restore into an isolated test database (the test/database harness) so it cannot touch real data.
2. Scheduling makes e2e tricky. Tests should drive the API (create backup, list, status) rather than waiting on cron; the schedule itself stays unit-covered.

Acceptance criteria

• An e2e spec drives backup creation, listing, status, and restore against the test database.
• The spec runs in CI with the existing e2e harness without touching non-test data.

Out of scope

The durability fix (#42); unit coverage (#86).

Getting started

• test/database/ — the isolated test DB harness
• src/backup/backup.controller.ts — the endpoints

Commands: npm run test:e2e (or the repo's e2e script from package.json).

Good first files to read: test/database/prisma-test-helpers.ts, src/backup/backup.controller.ts.
