feat(v2): Phase 1 — map-first layout matching v1

Rebuilds the v1 map-centric experience in React:

Layout:
- 400px sidebar on left, interactive map on right (flex, 100vh)
- Exact same proportions and dark theme as v1

Sidebar (top→bottom):
- Header with active player count + Dashboard toggle button
- Server status dot (Coldeve online/offline with pulse)
- Aggregate counters: Rares (gold), Server KPH (blue glow), Kills (red)
- 6 sort buttons (Name, KPH, S.Kills, S.Rares, T.Kills, KPR)
- Player name filter
- Scrollable player list with per-row:
  - Name + coordinates
  - HP/Stamina/Mana vital bars (red/orange/blue gradients)
  - Session kills, total kills, KPH
  - Session rares, total rares, VTank meta state pill
  - Online time, deaths, prismatic tapers
  - Color-coded left border per player

Map:
- dereth.png with CSS transform pan (drag) + zoom (wheel, 1.1x factor, max 20x)
- Player dots (6px circles, color-matched to sidebar)
- Hover tooltip (name, coords, kph, kills)
- World coordinate display at cursor position
- Fit-to-window on first load

View toggle: Map View ↔ Dashboard with localStorage persistence.
All v1 CSS ported under ml-* prefix, scoped via map-layout.css.
