Make Ideas Upgradable

[gruz0]

We need the ability to upgrade ideas from outdated states to the newest state possible.

Here is a scenario: a customer created an idea two weeks ago, and since then, we've added new functionality, but their idea hasn't been updated since its creation date. For example, it might lack new options or data introduced after its creation.

To address this, we need to implement a new endpoint: /api/ideas/:id/upgrade. This endpoint will be triggered by a button on the frontend, allowing customers to upgrade their ideas to the latest version.
