Fix
- IMP40 station buttons: Fixed duplicate
unique_id error when two station names sanitize identically (e.g. "Dance Hits" and "Dance Hits!"). The pointer is now included in the unique ID for guaranteed uniqueness.
- Deduplication: IMP40 favourites list is now deduplicated by pointer before creating button entities.
⚠️ Note: After updating, existing IMP40 station button entities will be recreated with new unique IDs. The old orphaned entities can be removed manually via Settings → Devices & Services → Entities.
