feature(Popups): Conditional User Defaults Implementation

Implement conditional defaults for user preferences in the Popups
component.
This patch aims to simplify the preference management system by
leveraging conditional logic directly within the component rather
than relying on multiple hooks

Changes:
- Updated `extension.json` to reflect the removal of outdated hooks.
- Updated `extension.json` to reflect the conditional user defaults.
- Removed unused user option `popupsreferencepreviews` from
 `extension.json`
- Modified `PopupsHooks` to streamline the preferences management,
 and depend on conditional user defaults, and removing `onUserGetDefaultOptions` and `onLocalUserCreated` hooks.
- Removed unneeded test cases in `PopupsHooksTest`.

Bug: T364347
