Fix: Multiple TeleBot UI improvements

1. Remove /help from main menu
   - Removed "❓ Help" button from main menu
   - Help still available via /help command

2. Fix support refresh clearing messages
   - Changed from editing message to sending new message
   - Preserves message history when refreshing
   - Shows "No new messages" if no updates instead of clearing
   - Better error handling with user-friendly alerts

3. Add retry payment button for failed payments
   - New "🔄 Retry Payment" button when payment creation fails
   - Shows order ID (friendly reference) in error message
   - PaymentFailedMenu: Retry, View Basket, Main Menu options
   - HandleRetryPayment: Re-shows currency selection
   - Preserves order and allows payment retry without recreating order

Technical Changes:
- MenuBuilder: Added PaymentFailedMenu method
- CallbackHandler: Added retry_payment case and HandleRetryPayment method
- HandlePayment: Updated error messages to use PaymentFailedMenu
- HandleRefreshConversation: Sends new message instead of editing
