feat: Add Phase 5 customer store frontend

Build public-facing e-commerce interface for server owners' item stores.

Components:
- StoreView.vue (420 lines): Full customer purchase flow
  * Dynamic category filtering
  * Responsive 4-column grid (mobile-first)
  * Professional card design with hover effects
  * Purchase modal with Steam ID validation (17 digits)
  * PayPal redirect flow (new window)
  * Empty/error/loading states

Features:
- Steam ID input with regex validation
- Player name input (optional)
- Purchase limit enforcement
- Item type badges (kit/rank/currency/command)
- Legal disclaimer with auto-delivery notice
- Mobile-responsive professional design
- Gradient background, shadow effects, transitions

API Integration:
- GET /api/public-store/:subdomain (store info)
- GET /api/public-store/:subdomain/items (catalog)
- POST /api/public-store/:subdomain/purchase (PayPal order)

Security:
- Public route (no auth required)
- Subdomain-scoped queries
- Steam ID validation before submission

TypeScript:
- PublicStoreInfo, PublicStoreItem
- StorePurchaseRequest, StorePurchaseResponse

Items auto-deliver via NATS webhook after payment completion.
