## Description
This PR addresses issue #7110, where Airtable, Stripe and PostgreSQL
integrations were showing as "Soon" under Settings > Integrations.
## Changes
- Update `getSettingsIntegrationAll` so that when these integrations are
disabled (via feature flags), they are removed from the list instead of
showing as "Soon".

- Tweaked `useSettingsIntegrationCategories` to only show the "All"
category if there's at least one integration enabled.

## Notes
This is my first contribution to the project, so I'm open to feedback! 😄
Let me know if there's anything I should tweak or improve.
Our tests on FE are red, which is a threat to code quality. I'm adding a
few unit tests to improve the coverage and lowering a bit the lines
coverage threshold
