Scripts Absorbed Into FractalOps

Legacy ad-hoc scripts were absorbed into the FractalOps operation runtime.

Use:

uv run fractalops operations list
uv run fractalops operations run --operation-id <id> --ssot-json '{}'
uv run fractalops operations audit --source-dir scripts

Primary replacements:

Legacy catalog/deploy/setup scripts -> uv run fractalops operations run with existing operation IDs
ssh-deploy -> uv run fractalops operations run --operation-id ssh_deploy
start-qemu-agent -> uv run fractalops operations run --operation-id start_qemu_agent

This keeps operation logic in one place (backend/src/fractalops/application/integration) and avoids script drift.
