v3.30.0: the batch status modal

A running batch now shows in a modal window (the same chrome as the
single-operation modal): the live status on top - the current step from
ram_progress (Step n/N - <step>, with the bar) or the waiting prompt
("Insert next card. Waiting for a card...") - plus the counts and the
last finished card's verdict, and the processed cards below (the same
attempts table with the per-step verdicts).

It opens on Start and on a page load with a run in flight (the first
poll sees ram_batch.active); Close is disabled until the run ends (the
run is server-side and survives a reload - that is what reopens the
window), and Stop/Clear live inside it (Clear only once the run ended).
The panel's new Show status button reopens a finished report.  A single
operation takes the modal back; ramBatchRender feeds both the panel and
the modal (the poll's fetch decision now runs for either).

Docs: help EN/RU, the repo AGENTS.  Tests: the open on Start and on the
poll, the live status/bar/counts/attempts, the close guard (active vs
ended), the reopen button.  929 frontend + 945 Python; sw cache
