Add actor-level tracing span in worker tick_all to propagate actor_addr
to user log events. DashboardLayer now extracts actor_addr from both
span extensions and event fields. EventStore gains read_for_actor() for
filtered log queries.
Web actor detail page gets a live-updating log panel with per-level
filter buttons (ERR/WARN/INFO/DBG/TRC) and auto-scroll. TUI actor
detail view adds scrollable log panel with j/k navigation and 1-5 keys
for level toggling. REST endpoint at /api/logs?actor=<hex>&limit=N&level=L.
