Pass 3 next slice: snapshot polish, analytics depth, player drawer

- Snapshots now include recursive sizeBytes (lib/snapshots.ts dirSize),
  rendered as a badge next to mod count.
- Snapshot restore/delete is now type-to-confirm: click Restore/Delete,
  type the literal snapshot name, press Enter or click Confirm. Esc
  cancels, matches the existing wizard Esc handler.
- Analytics card:
  - Uptime ring showing % of datapoints with tps>0 (color-graded
    green/amber/red) + numeric % over selected range.
  - Peak-player marker dot on the Players sparkline + peak caption.
  - "Online now" player list (up to 8) with small PlayerAvatar badges,
    sourced from the latest analytics entry's players[] array.
- Player profile drawer (new):
  - Slide-in right panel opened by clicking any PlayerAvatar.
  - Shows Online / Op / Whitelisted / Banned badges, UUID, ban reason.
  - Quick toggles for op/deop, whitelist add/remove, ban (with reason
    input) and pardon — reuses /api/players POST contract.
  - Global event bus (lib/events.ts) decouples avatars from drawer.
  - Esc / backdrop / close-button dismiss.
- PlayerAvatar now renders as a <button> by default (stopPropagation on
  click, focus-visible ring); pass interactive={false} to opt out (used
  inside the drawer itself).
