feat(label): add syncLabels method to BaileysStartupService

Uses Baileys client.resyncAppState(['regular'], true) to force
an incremental re-download of WhatsApp app state (labels).
Waits 3s for LABELS_EDIT/LABELS_ASSOCIATION event handlers to
process, then returns updated labels from DB via fetchLabels().

Key: isLatest=true means incremental (safe, no disconnect).
isLatest=false would download full snapshot and cause disconnection.
