Add POST /api/v1/providers/test endpoint (#406)

Browse source 
## Summary

Adds `POST /api/v1/providers/test` so API, CLI, and UI callers can check
LLM provider health without parsing `/health/diagnostics`. The endpoint
tests every configured provider once using the catalog probe model and
returns typed, per-provider results with an aggregate summary — all at
HTTP 200, with provider failures expressed in the body.

This PR also adds `scheduler_slots_used` to `SystemRunCounts` to
distinguish runs occupying concurrency slots from all "active" runs
(e.g. runs blocked waiting for human input count as active but do not
hold a scheduler slot).

### What changed and why

**Provider probe logic** (`diagnostics.rs`)

The inline probe loop inside `check_llm_providers` was extracted into
`test_llm_providers` / `probe_single_provider`, which both the new
endpoint and the existing diagnostics check now share. The extraction
preserves the diagnostics output format: `diagnostic_detail` (a
`#[serde(skip)]` field) carries the richer context string used for the
`LLM Providers` section, while `error_message` carries the redacted,
public-facing error.

Key decisions:
- `ProviderProbeStatus` is `ok | error` only — no `skip`, because v1
only iterates configured providers.
- `model_id` is nullable so auth/registration failures (where no probe
was sent) can be expressed cleanly.
- API key values appearing in upstream error responses are passed
through `redact_string` before being stored in `error_message`.

**Route** (`handler/models.rs`)

`.route("/providers/test", post(test_providers))` added alongside
`/providers`, protected by the same `RequiredUser` extractor.

**`scheduler_slots_used`** (`handler/system.rs`, `server.rs`)

The status predicate (`Starting | Running | Blocked | Paused`) was
already duplicated between the scheduler loop and `get_system_info`.
It's now a named function `counts_toward_scheduler_capacity`, used in
both places and in the new `SystemRunCounts` field. The web UI
monitoring panel was updated to display "slots used" instead of
"active."

**Generated clients**

OpenAPI spec updated; Rust and TypeScript clients regenerated. New
TypeScript types: `ProviderTestList`, `ProviderTestResult`,
`ProviderTestStatus`, `ProviderTestSummary`.

### Plan Summary

- Add `testProviders` OpenAPI operation and `ProviderTestList` /
supporting schemas to `fabro-api.yaml`.
- Extract shared `test_llm_providers` from `check_llm_providers` in
`diagnostics.rs`; keep diagnostics output identical.
- Wire `POST /providers/test` handler in `handler/models.rs`.
- Add `scheduler_slots_used` to `SystemRunCounts` and extract
`counts_toward_scheduler_capacity` predicate.
- Regenerate Rust and TypeScript API clients.
- Add integration tests covering: no providers, successful probe, auth
failure (no upstream call), registration failure, mixed catalog order,
and API key non-leakage.
