Check plan/features

[jpaulet]

As Vocdoni, we need a system to verify if an organization has the necessary features enabled and if it adheres to specific usage limits based on its subscription tier.

Acceptance Criteria:

• Subscription Tiers: Each subscription tier (e.g., Pro, Premium) must define a set of features and usage limits.
  Example structure:

    {
      "pro": {
        "max_admins": 3,
        "max_suborgs": 3,
        "voting_types": {
          "single_choice": true,
          "multiple_choice": true,
          "approval": true,
          "ranked": false,
          "participatory_budgeting": false
        },
        "features": {          
          "sms_census": false,
          "email_census": false,
          "personalization": true,
          "domain": true,
          "redirect_after_voting": true,
          "texts_customization": false
        }
      }
    }

Organization Subscription Linkage:

• Each organization must be linked to a specific subscription plan.

Feature and Limit Validation:
When an admin attempts to:

• Add more admins or sub-organizations
• Enable or configure a feature
• Perform any action restricted by the subscription plan

The system must first check if the action complies with the organization’s current subscription tier.

Upgrade Path:
If the action exceeds the allowed limits or if the feature is not enabled:

• Display an "Upgrade Plan" popup, highlighting the benefits of higher tiers.
• Provide a clear path to upgrade the subscription.
