feat(picloud): opportunistic principal middleware on the data plane

The data-plane (POST /execute/{id} + user-route fallback) is
unauthenticated by default — public scripts get hit by anonymous HTTP
traffic. But some calls are authed (dashboard test-runs, API-key
invocations) and v1.1.x services will want to see the caller via
`cx.principal` for audit / authz once those features land.

  - New manager-core::attach_principal_if_present middleware. Always
    inserts Extension<Option<Principal>>: Some on resolved bearer/cookie,
    None on absent or malformed token. Fail-open on DB blip so a
    transient infra failure can't 500 anonymous traffic.
  - Wired in picloud build_app, scoped to the data-plane and user-routes
    routers only. The admin path keeps using require_authenticated; no
    double-resolve on the same token.
  - orchestrator-core handlers (execute_by_id, user_route_handler) now
    extract Extension<Option<Principal>> and pass it to build_exec_request.
    Replaces the temporary `None` placeholders from the previous commit.
