EthanHealy01 caeca0b88a Fix classification escalation: the local pass was claiming the server dispatch key (#7667)
Follow-up to #7580: the escalation it added could never fire.

## What's broken

The auto-run skips a policy that has already run on a file, keyed on
`(categoryId, fileId)`. `recordRunStart` claims that key — and #7580 has
the **browser-side first pass** record its own run under `categoryId:
"classification"` for the uploaded file. So the local heuristic ticks
the very key the server escalation checks, and the AI is never asked, at
any confidence.

Trigger is the default seeded setup: **Classification as the only
on-upload policy**, and a local verdict below `high`. Any other
on-upload policy masks it, because classification then targets that
policy's output — a new file id whose key was never claimed. That's why
this went unnoticed.

Two smaller faults in the same path:

- A chained output carried no `classificationConfidence`, so
`shouldDispatchToAi` waited for a verdict that could never arrive (a
tool-derived file gets no local pass).
- Browser-local runs were polled against the server: 3 × 404 per file,
after which `MAX_NOT_FOUND` marked a local run that had actually
**succeeded** as `FAILED`.

## The fix

- `PolicyRunRecord.browserLocal`; `recordRunStart` skips the dispatch
claim for such a run. It is the first pass, not the policy's run.
- The local pass meters under `classification:local-meter` instead of
the category id, so metering dedupe survives without suppressing
dispatch.
- The poll effect skips browser-local runs.
- `CONSUME_FILES` inherits `classificationConfidence` alongside the
labels, so the verdict survives a version bump.

## How to test

Download
[`low-confidence-classification.pdf`](https://github.com/Stirling-Tools/Stirling-PDF/raw/fix/chained-classification-confidence/frontend/editor/src/proprietary/services/heuristic/fixtures/low-confidence-classification.pdf)
(checked in as a fixture, verdict pinned by a test).

With **Classification as the only on-upload policy**, upload it and
watch the Network tab:

- **Before:** no `POST /api/v1/policies/{id}/run` for classification,
ever. Console shows `local-classification-*` 404s.
- **After:** exactly one, and the engine receives `POST
/api/v1/documents/classify`.

Judge it on that request, not on the resulting label — the model's
answer varies, so a label comparison can pass or fail for the wrong
reason.

Headless equivalent:

```
npx vitest run --project proprietary src/proprietary/components/policies/usePolicyAutoRun.escalation.test.tsx
```

Passes here, fails on `main` on "asks the AI about an unsure verdict
even though the local pass already ran". Its other two cases pass on
both, so the guards still hold: a confident verdict still costs nothing,
and a file with no verdict yet still waits rather than racing the free
pass.

New tests drive the **real** run store — mocking it is what let this
through.
