v3.30.2: the batch RU wording sweep completed

The v3.30.1 review follow-up.  The sweep fixed the two batch-state
strings but two more shared (kind-independent) batch strings were still
install-specific, so a delete/reinstall batch started under an "install"
label:

- 'Start batch' was «Запустить пакетную установку» - the ram-batch-start
  button starts every kind - now «Запустить пакетную операцию» (aligning
  with the optgroup «Пакетные операции (по картам)»).
- the shared panel hint's «...перезапустите пакетную установку» is now
  «...перезапустите пакетную операцию» (the EN was already neutral).

The RU help quoted the old button label: its install row now says
«Запустить пакетную операцию не требует карты», and the row's other
generic "the batch" statements (never retries, the test-run exclusion)
are neutral too; the genuinely install-specific ones (the workflow, the
shared install form) stay.

The v3.30.1 notes were corrected: the counts labels do follow the last
run's kind after a clear (the values stay zero) - the AGENTS entry and
the _ramBatchLastKind/ramBatchRender comments say so now.  The
cleared-title test seeds the state before opening the modal (no reliance
on the previous test's sandbox leftovers).
