Add /markets page with tabbed market data display

[Copilot]

Previously /markets redirected to coinmarketcap. Users need integrated market data viewing without context switching.

Changes

• New markets package: Handlers for HTML/JSON responses, reuses existing widgets.GetAllPrices() data
• Tabbed interface: Crypto (10 assets), Futures (4 commodities), Commodities (5 agricultural)
• Sidebar integration: Added Markets navigation link between Video and Wallet
• Responsive grid layout: Card-based design with hover states, mobile-optimized
• Public route: No auth required, supports content negotiation via Accept header

Implementation

// Handler dispatches based on category query param and content type
func Handler(w http.ResponseWriter, r *http.Request) {
    category := r.URL.Query().Get("category")  // crypto|futures|commodities
    if category == "" {
        category = CategoryCrypto
    }
    
    if app.WantsJSON(r) {
        handleJSON(w, r, category)
        return
    }
    handleHTML(w, r, category)
}

Data sources unchanged: Coinbase API (crypto), Yahoo Finance (futures/commodities) with hourly refresh.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
