Test the route through run and verify session authorization.

The test calls resolve_session_channel and send_message directly. It does not exercise run, which owns the required setup order. A regression that removes or reorders the resolution at Line 501 can pass this test. The test also does not assert the Authorization header on GET /api/webchat/v2/session. Drive the flow through its caller and assert Bearer session-token.

As per path instructions, “Test through the caller: when a helper gates a side effect, require a test driving the real call site.”

In `@tools/ironclaw_stress/src/api_capacity.rs` around lines 3159 - 3215, Update
regression_message_send_uses_advertised_session_channel_route to exercise the
public run flow instead of calling resolve_session_channel and send_message
directly, preserving the setup order owned by run. Extend the session-request
assertions to verify the GET request includes Authorization: Bearer
session-token, while retaining the existing advertised channel route and
message-body checks.
