fix(09.2): read tunnel label from the relay's tags field

Live smoke: picker showed 'No Vector-agent tunnels yet' though the agent's
tunnel was listed and hosting. The relay returns the label under `tags`, not
`labels` (the SDK maps Tunnel.labels -> tags in the default api-version), so
TunnelRecord.labels deserialized empty and is_vector_agent() was always false.

Add `#[serde(alias = "tags")]` so labels reads either key; make the list
fixture realistic (`tags`). Regression test deserializes a real-shaped record.
