[IOPID-2598] Tracking offline event (#6606)

## Short description
This PR adds the tracking of the `INGRESS_NO_INTERNET_CONNECTION` event,
logged when the user opens the app with the internet connection
disabled.

## List of changes proposed in this pull request
- Added and implemented the `INGRESS_NO_INTERNET_CONNECTION` event
- Added the `event_category: KO` to the already existing
`INGRESS_SERVICES_SLOW_DOWN`, `INGRESS_TIMEOUT` and
`INGRESS_CDN_SYSTEM_ERROR` events

## Demo

## How to test
Start the app ensuring that the internet connection is disabled (as
shown in the demo). Once the blocking screen appears, close the app,
re-enable the internet connection, and reopen the app.

>[!Note]
>In this demos, I'm using [Proxyman](https://proxyman.io/) to monitor
internet traffic, but any tool of your choice can be used.
