fix: backup automation mock + Claude probes dashboard alias (#2293)

## Summary
Full Suite after #2292: shards 1–3 green; shard 4 failed FN-7537 backup
automation tests with `store.getGlobalSettingsDir is not a function`.

- Add `getGlobalSettingsDir` to routes-automation mock store
- Point backup-parity fixtures’ global dir at the temp fusion dir
- Dashboard Vitest: alias `@fusion-plugin-examples/claude-runtime` →
`probes-entry` (same class as CLI #2292)

## Test plan
- [x] Local manual backup run parity (4 tests)
- [ ] PR gate
- [ ] Post-merge Full Suite

## Summary by CodeRabbit

* **Bug Fixes**
* Improved automation backup test coverage for global backup directory
handling.
* Preserved reliable manual backup behavior and event ordering across
supported automation steps.
* Fixed dashboard API test configuration for Claude runtime probe
resolution.
