feat: add XCM teleport and CI/CD deployment workflow

Features: - Add XCMTeleportModal for cross-chain HEZ transfers - Support Asset Hub and People Chain teleports - Add "Fund Fees" button with user-friendly tooltips - Use correct XCM V3 format with teyrchain junction Fixes: - Fix PEZ transfer to use Asset Hub API - Silence unnecessary pallet availability warnings - Fix transaction loading performance (10 blocks limit) - Remove Supabase admin_roles dependency CI/CD: - Add auto-deploy to VPS on main branch push - Add version bumping on deploy - Upload build artifacts for deployment
