Enhance WebHook "Feature updates" event with human-readable data and change diff

[dufasky]

Hello, Dear Colleagues!
Glad to write to you!

Currently, when the "Feature updates" WebHook event is triggered, the request contains the following limitations:

1. The payload includes all feature flags instead of just the diff between previous and new versions
2. Only portfolio/application/environment IDs are provided, making it difficult to identify them for different communication channels
3. No "before/after" change representation is available

Suggested Improvement:

1. It would be extremely helpful to receive WebHook events in a more informative format that includes:
2. Human-readable names (portfolio, application, environment)
3. Only changed features (with version diff)
4. Clear "before/after" change structure
5. Audit information about who made changes and when
6. This proposal is very useful for informing in different communication channels.

Example of Desired Payload in WebHook:

  "portfolio": {
    "name": "portfolioName",
    "id": "uuid"
