Add fingerprint-based detection for duplicate device registration with configurable behavior via new body params: - allow_existing: return existing device if fingerprint matches - allow_duplicate: skip fingerprint check, always create new device - reset_syncs: clear tracked saves when reclaiming existing device Fingerprint matching uses mac_address (primary) or hostname+platform (fallback). Returns 409 Conflict with device_id when duplicate detected without flags, 200 OK for existing device, 201 Created for new.
