- live detection: use !h.status (null while running) not === 'running'
- SSE: replace named addEventListener('chunk'/'done') with onmessage +
frame.done check — backend sends generic message events, no named type
- SSE payload: use frame.stdout_append/stderr_append not frame.text
- timestamps: started_at/finished_at are unix seconds, multiply by 1000
was already done implicitly — actually use unix arithmetic directly
to avoid new Date() confusion entirely
Also move the misplaced .flow-main-slim rule from the logs section to
the flow-shell section of dashboard.css.
