Updated the Network List Connect button icon on GTK3 to use the bundled zc-menu-connect asset, which avoids theme-dependent missing network-connect behavior.

Added a Help menu _Update entry with a dedicated zc-menu-update icon constant, so Windows builds can display an appropriate update icon in the Help menu.

    Extended icon mapping/fallback logic so emoji/update icons resolve correctly across stock/icon-name paths (zc-menu-emoji, zc-menu-update) including GTK2 stock fallback compatibility.

    Added zc-menu-emoji to the input entry fallback icon list so the emoji affordance has a deterministic built-in fallback when theme emoji icons are missing.

    Added new update and emoji icon assets in both SVG and PNG for light/dark variants, and registered the PNG resources in the gresource manifest for runtime loading.
