fix: respect DATABASE_SAVE_DATA_CONTACTS in contact updates

- Added missing conditional checks for `DATABASE_SAVE_DATA_CONTACTS` in `contacts.upsert` and `contacts.update` handlers.
- Fixed an issue where profile picture updates were attempting to save to the database even when disabled.
- Fixed an unawaited promise in `contacts.upsert` to ensure database operations complete correctly.
