frontend: Escape "&" in non-hardcoded menu items

"&" is used to make shortcuts for menu items, so we need to escape non-hardcoded items with "&&".

Applies escaping for these menus:
- profiles menu
- scene collections menu
- projector names
- transitions menu (for plugins)
- filters menu (for plugins)
