[compose] Improved reliability of attribution list updates on source change. (#9965)

Fixes https://mapbox.atlassian.net/browse/MAPSAND-2527

## Problem
Before mapbox/mapbox-sdk#9411, there was no
reliable way to detect when map attributions changed. This affected
scenarios where:
- Sources are added at runtime.
- Standard styles are loaded with dynamic sources.
- Style imports modify attributions.

Since internal style source details are not exposed through public APIs,
the attribution UI could become stale and show incorrect licensing
information.

## Solution
This PR utilizes the new `StyleAttributionsChangedCallback` introduced
in mapbox/mapbox-sdk#9411 as the source of truth
for attribution changes. This ensures the attribution list UI updates
correctly in all scenarios, including edge cases not covered by the
previous implementation.

## Changes
- Integrated `StyleAttributionsChangedCallback` to listen for
attribution changes.
- Updated attribution list refresh logic to trigger on callback events.
- Improved reliability of attribution display in the Compose extension.
