Summary

As a first step for offering configurable share buttons (PLANET-7609), we should offer a settings page where admins can select to hide one of the existing options.

Requirements

• A new setting under Planet 4 > Social
  • Label: "Choose social sharing options"
• This should be a multiple selection option field (checkboxes), showing the 4 sharing options we already have (WhatsApp, Facebook, X, Email).
• We should create a migration to have those options enabled by default
• Settings should also apply on the Gravity Forms Share button settings
  • Remove the current customization menu
  • Native share should still be displayed in mobile
  • We can keep the text fields for custom share url/text
• Adjust the social sharing template to dynamically include the selected options
