refactor: Remove inbound IP allowlisting (#443)
## Summary

Removes Fabro's in-process inbound source-IP allowlist entirely.
`[server.ip_allowlist]` and
`[server.integrations.github.webhooks.ip_allowlist]` are gone from
config parsing, resolved settings types, the OpenAPI spec, generated API
clients, and the Settings > Security UI. Existing `settings.toml` files
containing those keys now fail as unknown fields — this is a hard
removal with no migration path.

Network source restrictions should be enforced upstream via a reverse
proxy, firewall, VPN, Tailscale ACLs, Kubernetes ingress, or platform
policy.

### What changed

- **Config/types** (`fabro-config`, `fabro-types`): Removed
`ServerIpAllowlistLayer`, `ServerIpAllowlistOverrideLayer`,
`ServerIpAllowlistSettings`, `ServerIpAllowlistOverrideSettings`,
`IpAllowEntry`, associated resolver functions, GitHub `/meta` hook-range
parsing, and Unix socket trusted-proxy validation. `ipnet` dropped from
`fabro-types`; kept in `fabro-config` for sandbox CIDR validation.
- **Server runtime** (`fabro-server`): Deleted `ip_allowlist.rs`,
removed `IpAllowlistConfig` parameter from `build_router_with_options`
and `RouterOptions`, removed the global allowlist middleware layer, and
removed `GitHubMetaResolver` startup logic. GitHub webhook HMAC
verification is unchanged.
- **OpenAPI + generated clients**: Removed `ServerIpAllowlistSettings`,
`ServerIpAllowlistOverrideSettings`, `IpAllowEntry`,
`LiteralIpAllowEntry`, `GitHubMetaHooksEntry` schemas; removed
`ip_allowlist` from `ServerNamespace` and `IntegrationWebhooksSettings`;
dropped `IpAllowEntry` re-exports from `fabro-api`.
- **Web UI**: Removed IP allowlist row from Settings > Security; updated
nav description and page copy.
- **Docs/changelog**: Security docs explicitly state Fabro provides no
source-IP filtering and direct operators upstream. Changelog entry dated
2026-05-27 documents the breaking removal and annotates the 2026-04-19
entry where the feature was introduced.

### Also in this diff (unrelated to IP allowlisting)

The worker control stream was migrated from reading newline-delimited
JSON on stdin to a reconnecting WebSocket
(`/api/v1/runs/{id}/worker/control-stream`). This adds
`tokio-tungstenite` to `fabro-cli`/`fabro-server`, introduces
`WorkerControlManagerHandle` with backoff reconnection and deduplication
of replayed delivery IDs, and adds `RunPause`/`RunUnpause` message
handling. A new integration test
(`detached_run_cancel_reaches_worker_over_control_websocket`) exercises
the full cancel path over the WebSocket.

### Key decisions

- **Hard removal via `deny_unknown_fields`**: stale config is
immediately visible as a startup error rather than silently ignored.
- **No stub or default pass-through**: `IpAllowlistConfig::default()` is
gone, not left as a no-op wrapper, to avoid keeping the feature shape
alive.
- **Webhook HMAC boundary unchanged**: source-IP filtering on webhook
routes is removed; cryptographic signature verification remains the
security boundary.
