feat: cutter/merge i18n + per-item retry + status-bar queue summary

Three Phase-6 wins.

1. Cutter & Merge tab labels were the same i18n gap as the trim-VOD
   dialog before 4.5.20: Dauer / Aufloesung / FPS / Auswahl / Start: /
   Ende: / Schneiden / Zusammenfuegen were hardcoded German in
   index.html. Each got an id + setText wiring + DE/EN locale strings
   (cutter.infoDuration / .infoResolution / .infoFps / .infoSelection
   / .startLabel / .endLabel; cutter.cut + merge.merge already existed
   for dynamic state, now also used as initial text on btnCut /
   btnMerge).

2. Per-item retry button on failed queue entries. The existing
   "retry failed" queue-action retried ALL failed items at once;
   when only one specific item should be retried (e.g. transient
   network blip on one URL), the user had to remove every other
   failed item first. New ipcMain.handle("retry-queue-item", id)
   resets that single item to status: pending and triggers
   processQueue if idle. A small ↻ icon now sits next to the
   remove (x) button on items in the error state.

3. Status bar queue summary. The footer previously showed only the
   connection status + version. With longer queues the user had to
   scroll the queue panel to see how many downloads were active
   versus pending. New span between the status indicator and the
   version reads "{downloading} dl, {pending} queued" (locale-aware,
   hidden when queue is empty). Updated on onQueueUpdated and
   onDownloadProgress so it stays live.
