feat: stats-bar pause-on-hidden + bulk-mark downloaded + title tooltip

Three Phase-13 wins.

1. Stats bar polling pauses while document.hidden. Previously
   setInterval(updateStatsBar, 5000) ran forever, including while
   the user had a different tab focused or the window minimised.
   Now wraps start/stopStatsBarPolling and listens to
   visibilitychange. When the page becomes visible the interval
   restarts; while hidden it sleeps. Saves an IPC round-trip every
   5s when nobody's looking.

2. Bulk mark / unmark "as downloaded" on the VOD bulk-bar. Companion
   to the per-card right-click context menu's mark/unmark items —
   when the user has 5 VODs selected they now get one click to
   toggle the green check on all of them instead of right-clicking
   each. Uses the existing markVodDownloaded IPC, refreshes the
   local config copy + re-renders the grid so badges update live.

3. VOD card title tooltip. The card title is text-overflow:ellipsis
   so longer titles get cut off. Adding title="${full title}"
   surfaces the full text on hover via the native browser tooltip
   — no custom UI needed.
