### Summary by CodeRabbit

**New Features:**
- Added WhatsApp integration feature to the Pro plan.

**Refactor:**
- Introduced the ability to exclude specific plans from being displayed
in the Change Plan Modal.
- Renamed the function `isProPlan` to `hasProPerks`, enhancing code
readability and maintainability.
- Updated the `EmbedButton` component to handle a new `lockTagPlan`
property and use the `modal` function instead of the `Modal` component.

**Chore:**
- Removed the `whatsAppPhoneNumberId` field from the `Typebot` model
across various files, simplifying the data structure of the model.
