feat(server): add GET /api/v1/providers and /settings/models page (#321)
## Summary

Operators had no UI surface to see which LLM providers their Fabro
server has configured — provider state was only inferable indirectly via
the per-model `configured` flag on `GET /api/v1/models`. This adds a
dedicated **Models** settings tab backed by a new providers endpoint.

- **`fabro_model::Provider`** — a public projection of the internal
`CatalogProvider` that *structurally* excludes credential-bearing fields
(`auth`, `extra_headers`, `billing_policy`, `agent_profile`). Reused by
the generated API client via progenitor `with_replacement`, mirroring
the existing `Model` pattern — no parallel API DTO.
- **`GET /api/v1/providers`** — lists catalog providers with effective
config and a `configured` status stamped per request from
`ready_llm_provider_ids()`. Sorted by the catalog's existing
`provider_order`. No write endpoints.
- **`/settings/models` web page** — new route + nav entry
(`CpuChipIcon`, between Integrations and Security) rendering each
provider with model count, default model, configured status, and a "Get
API key" link for unconfigured providers.

## Key decisions

- Provider sort: reuse catalog `provider_order` (priority desc, id asc)
— zero extra code.
- `adapter` is hidden in the UI row (noisy for first-party providers);
the OpenAPI `adapter` field is pinned to an enum matching the closed
`AdapterKind` type.
- `configured` reflects credential resolution **at the time of the
response**, not a frozen startup snapshot — doc/spec wording corrected
to match.

## Testing

- `fabro-model`: `From<&CatalogProvider>` + serde `skip_serializing_if`
unit tests.
- `fabro-api`: `Provider` type-identity + JSON-parity tests, including
the required/optional field split.
- `fabro-server`: handler tests for configured vs unconfigured
providers, exact `model_count`/`default_model` against catalog truth,
and credential-omission (asserts internal field names *and* the injected
credential value never reach the wire).
- OpenAPI route conformance test covers `GET /api/v1/providers`.
- `cargo build --workspace`, `fmt --check`, `clippy -D warnings` clean;
935 Rust tests pass; web `tsc` typecheck passes.
- Reviewed via a 10-persona `ce:review` (autofix) — no P0/P1 in shipped
code; 8 safe fixes applied.

Not done: manual UI screenshots — the `apps/fabro-web` build is blocked
in this environment by an unrelated missing `@assistant-ui/react`
dependency. Run `bun install` in `apps/fabro-web` to verify
`/settings/models` manually.

## Post-Deploy Monitoring & Validation

- **What to watch:** request logs for `GET /api/v1/providers` — expect
`200`s for authenticated users, `401` for unauthenticated. The handler
resolves LLM credentials per request via `ready_llm_provider_ids()` (the
same path the existing `list_models` handler already uses).
- **Healthy signals:** `/settings/models` renders the provider list;
`configured` matches each provider's actual credential state; no
credential strings appear in any response body or log line.
- **Failure signals / rollback trigger:** any provider object in the
response containing `auth`, `extra_headers`, or a raw key/token value →
roll back immediately (the projection type makes this structurally
impossible, but treat any occurrence as P0). 5xx spikes on the new
route.
- **Validation window / owner:** first 24h after deploy, owned by the
deploying engineer. Pre-existing note (not introduced here): credential
resolution can refresh OAuth tokens and write the vault as a side effect
of this read — shared with `list_models`; flagged for a future caching
pass.
