fix: use shared host mount for answer files + rename to pve-integration

WORK_DIR now defaults to /opt/pve-integration/work (under the shared
host mount) instead of /tmp/pve-integration (container-local).

This fixes the answer server seeing empty answer files — the dev-infra
container writes answer files to WORK_DIR, and the answer server
container (a sibling) needs to read them from the same host path.

Also:
- Renamed mount from /opt/pve-isos to /opt/pve-integration
- Added must_run=true, start=true to answer server container
- Updated docker-compose.test.yml and dev.ps1 remote override
