feat: Addition of Half Signup

[AyakorK]

🎩 Description

Please describe your pull request.

This PR adds the "Half Signup" feature through middleware, allowing users to create a "partial" account using their email or phone number. This ensures easier voting while verifying user identity for each voting action. Additionally, untested overrides or not matching the last versions of it, such as User model extensions and the account/show.erb view, have been added to align with Decidim's release/0.27-stable branch, incorporating "Half Signup" adjustments like phone number editing.

SMS_GATEWAY_SERVICE="Decidim::SmsGatewayService"
SMS_GATEWAY_URL=<provider_url>
