feat(ui): shareholder-grade redesign + live "Your Club" account panel

- New theme.rs design system: palette, embedded fonts, egui Visuals/Style,
  card()/status_pill() helpers.
- Branded hero header (OF monogram), left nav rail, card-based dashboard,
  console-style Logs, themed Config tab, window/taskbar icon.
- New account_monitor.rs: background AccountMonitor (mirrors HealthMonitor,
  5s non-blocking poll) driving a live "Your Club" dashboard card (club
  name/abbr, manager, COINS hero number, level + XP bar, unopened packs,
  funds) with loading/offline/error states.
- account_sync.rs/app.rs/config.rs/main.rs wired to the monitor + theme.
  All existing launch/health/preflight/service/config logic preserved.
